Magnetic Order in FeCr2S4-Type Chalcogenide Spinels

Magnetoresistance between 160-185K,which includes the magnetic ordering temperature, has been observed in thiospinels of composition FeCr2S4 and Fe1+xCr2-2xSnxS4 in which tin occupies the octahedral B site

Nonadiabatic molecular alignment of linear molecules probed by strong-field ionization yields of photoelectrons [Book Chapter]

The dynamics of rotational wave packets of laser-aligned linear molecules were studied with femtosecond laser-driven strong-field ionization (SFI). The dynamics were observed as a function of the delay between a femtosecond probe pulse and a linearly polarized aligning pump pulse. The induced nonadiabatic molecular alignment was directly monitored by the total SFI yield. The measured revival signatures were compared to the calculated degree of molecular alignment taking into account the effects of electronic structure and symmetry of the molecules. By fitting the calculated alignment parameter to the measured experimental data, we also determined the molecular rotational constants of N 2 , CO, O 2 , and C 2 H 2 gas molecules. © The Editor(s) (if applicable) and The Author(s) 2018
