Roughness-induced magnetic decoupling at organic-inorganic interface
Hiroki Ono, Yoshitaka Umeda, Kaito Yoshida +8
We have investigated structural, electronic and magnetic properties of HPc on FeN/Fe using low-energy electron diffraction and soft x-ray absorption spectroscopy/x-ray magn…
Element-selective tracking ultrafast demagnetization process in Co/Pt multilayer thin films by the resonant magneto-optical Kerr effect
Kohei Yamamoto, Souliman El Moussaoui, Yasuyuki Hirata +8
We examined the photo-induced dynamics of ferromagnetic Co/Pt thin films demonstrating perpendicular magnetic anisotropy with element specificity using resonant polar magneto-optic…
Ultrafast demagnetization of Pt magnetic moment in L1-FePt probed by hard x-ray free electron laser
Kohei Yamamoto, Yuya Kubota, Motohiro Suzuki +15
We demonstrate ultrafast magnetization dynamics in a 5d transition metal using circularly-polarized x-ray free electron laser in the hard x-ray region. A decay time of light-induce…
Interference of the Bloch phase in layered materials with stacking shifts
Ryosuke Akashi, Yo Iida, Kohei Yamamoto +1
In periodic systems, electronic wave functions of the eigenstates exhibit the periodically modulated Bloch phases and are characterized by their wave numbers . We theoreti…
