Three-Dimensional Magnetic Page Memory

The increasing need to store large amounts of information with an ultra-dense, reliable, low power and low cost memory device is driving aggressive efforts to improve upon current perpendicular magnetic recording technology. However, the difficulties in fabricating small grain recording media while maintaining thermal stability and a high signal-to-noise ratio motivate development of alternative methods, such as the patterning of magnetic nano-islands and utilizing energy-assist for future applications. In addition, both from sensor and memory perspective three-dimensional spintronic devices are highly desirable to overcome the restrictions on the functionality in the planar structures. Here we demonstrate a three-dimensional magnetic-memory (magnetic page memory) based on thermally assisted and stray-field induced transfer of domains in a vertical stack of magnetic nanowires with perpendicular anisotropy. Using spin-torque induced domain shifting in such a device with periodic pinning sites provides additional degrees of freedom by allowing lateral information flow to realize truly three-dimensional integration

Relaxation of thermo-remanent magnetization in Fe-Cr GMR multilayers

The time decay of the thermo-remanent magnetization (TRM) in Fe-Cr giant magnetoresistive (GMR) multilayers has been investigated. The magnetization in these multilayers relaxes as a function of time after being cooled in a small magnetic field of 100 Oe to a low temperature and then the magnetic field is switched off. Low-field ($<$ 500 Oe) magnetization studies of these samples have shown hysteresis. This spin-glass-like behavior may originate from structural imperfections at the interfaces and in the bulk. We find that the magnetization relaxation is logarithmic. Here the magnetic viscosity is found to increase first with increasing temperature, then it reaches a maximum around T$_g$, and then it decreases with increasing temperature. This behavior is different from that of conventional spin glasses where the logarithmic creep rate is observed to increase with temperature. Power law also gives good fits and it is better than the logarithmic fit at higher temperatures. The dynamical effects of these multilayers are related to the relaxation of thermally blocked superparamagnetic grains and magnetic domains in the film layers.Comment: 19 page

Effects of rf Current on Spin Transfer Torque Induced Dynamics

The impact of radiofrequency (rf) currents on the direct current (dc) driven switching dynamics in current-perpendicular-to-plane nanoscale spin valves is demonstrated. The rf currents dramatically alter the dc driven free layer magnetization reversal dynamics as well as the dc switching level. This occurs when the frequency of the rf current is tuned to a frequency range around the dc driven magnetization precession frequencies. For these frequencies, interactions between the dc driven precession and the injected rf induce frequency locking and frequency pulling effects that lead to a measurable dependence of the critical switching current on the frequency of the injected rf. Based on macrospin simulations, including dc as well as rf spin torque currents, we explain the origin of the observed effects.Comment: 5 pages, 4 figure

The World Is Our Home: Society and Culture in Contemporary Southern Writing

Since the early 1970s southern fiction has been increasingly attentive to social issues, including the continuing struggles for racial justice and gender equality, the loss of a sense of social community, and the decline of a coherent regional identity. The essays in The World Is Our Home focus on writers who have explicitly addressed social and cultural issues in their fiction and drama, including Dorothy Allison, Horton Foote, Ernest J. Gaines, Jill McCorkle, Walker Percy, Lee Smith, William Styron, Alice Walker, and many others. The contributors provide valuable insights into the transformation of southern culture over the past thirty years and probe the social and cultural divisions that persist. The collection makes an important case for the centrality of social critique in contemporary southern fiction. Jeffrey J. Folks is professor of literature at Doshisha University in Japan. Nancy Summer Folks is a freelance editor with more than 15 years experience working with Southern literature. This book is an important text for the student of southern literature and history because each author examined is writing from the other side of the turbulent Fifties and Sixties, from having seen rural towns become burgeoning cities, and from having witnessed the politically disenfranchised attempt to join the mainstream. —Journal of the American Studies Association The essays challenge popular perceptions about the South and lend insight into the cultural and literary future of the region. —Book News The editors’ introduction succinctly summarizes a quarter-century of literary scholarship with a social focus. Strongly recommended. —Choice Multifaceted and illuminating. . . . These essays provide the kind of new critical perspectives southern fiction demands and deserves as it continues to depict social and cultural changes. The editors and essayists have paved the way for our understanding of the future of southern fiction. —David Madden These essays challenge popular perceptions about the South and lend insight into the cultural and literary future of the region. —Educational Book Review A satisfying collection of essays by scholars who have proved themselves as solid commentators in the field of southern literature. —Fred Hobson Reminds us, as have previous scholars of Southern literature, that the literature of the American South is much more varied and variegated than we often imagine. We should be thankful for this reminder. —Mississippi Quarterlyhttps://uknowledge.uky.edu/upk_english_language_and_literature_north_america/1063/thumbnail.jp

Brownian Motions on Metric Graphs

Brownian motions on a metric graph are defined. Their generators are characterized as Laplace operators subject to Wentzell boundary at every vertex. Conversely, given a set of Wentzell boundary conditions at the vertices of a metric graph, a Brownian motion is constructed pathwise on this graph so that its generator satisfies the given boundary conditions.Comment: 43 pages, 7 figures. 2nd revision of our article 1102.4937: The introduction has been modified, several references were added.

Adaptation and Aspiration: Constructing Modern Japan through Ideological Combat in Satsuma Rebellion Prints

Although past scholarship on Meiji-period prints has favored a clean evolution–from Yokohama-e to senso-e, samurai to soldier–this thesis considers two images of the Satsuma Rebellion that complicate both this historical transition and the art historical assessment of the woodblock medium. If the rebellion marked the “dress rehearsal” for imperial encroachment in Asia, I argue that woodblock prints offered mixed, preliminary reviews of Modern Japan. Between the eager curiosity of Yokohama-e and the self-exaltation of senso-e, Yoshitoshi and Shoso’s Satsuma Rebellion e-Sugoroku Game Board and Kunisada III’s War with the Western Nations mark the internal negotiation between competing notions of Japanese identity, as well as competing directions for the woodblock print – both in terms of pictorial style and social function. Through the analysis of sartorial vocabulary, technological innovation, and the pictorial stages on which these scenes play out, I explore this active negotiation staged through ink and paper.Master of Art
