Real-space observation of current-driven domain wall motion in submicron magnetic wires

Spintronic devices, whose operation is based on the motion of a magnetic domain wall (DW), have been proposed recently. If a DW could be driven directly by flowing an electric current instead of a magnetic field, the performance and functions of such device would be drastically improved. Here we report real-space observation of the current-driven DW motion by using a well-defined single DW in a micro-fabricated magnetic wire with submicron width. Magnetic force microscopy (MFM) visualizes that a single DW introduced in the wire is displaced back and forth by positive and negative pulsed-current, respectively. We can control the DW position in the wire by tuning the intensity, the duration and the polarity of the pulsed-current. It is, thus, demonstrated that spintronic device operation by the current-driven DW motion is possible.Comment: Accepted and published in PR

The Town leaders and of the residences of KYOWA 3 in the Tradesmen's Premises A Study on the Tradesmen's Premises in the Fukui Castle Town, part5

This paper compares of the town leaders and of the residences of KYOWA 3 in the tradesmen's premises. In what we sorted for each town, we were able to show the distribution of the clear town tuple. We showed the premises of the foreman of a gang who could identify it in the figure. Of the Machikumi, only the Jyonohashi-Machikumi was inside KURUWA. Of the 11 Machikumi, 128 towns were the most. There were few towns that belonged to the Machikumi in the center of the Castle. Most of the four Machikumi on the periphery of Fukui Castle ware local towns. The town leaders have not been hereditary by one family for generations.departmental bulletin pape
