Selective observation of surface and bulk bands in polar WTe2 by laser-based spin- and angle-resolved photoemission spectroscopy
Yuxuan Wan, Lihai Wang, Kenta Kuroda +12
The electronic state of WTe2, a candidate of type-II Weyl semimetal, is investigated by using laser-based spin- and angle-resolved photoemission spectroscopy (SARPES). We prepare t…
Reduced magnetocrystalline anisotropy of CoFeO thin films studied by angle-dependent x-ray magnetic circular dichroism
Yosuke Nonaka, Yuki K. Wakabayashi, Goro Shibata +9
Spinel-type CoFeO is a ferrimagnetic insulator with the Néel temperature exceeding 790 K, and shows a strong cubic magnetocrystalline anisotropy (MCA) in bulk materials. Ho…
Large Orbital Magnetic Moment and Strong Perpendicular Magnetic Anisotropy in Heavily Intercalated FeTiS
Goro Shibata, Choongjae Won, Jaewook Kim +7
Titanium disulfide TiS, which is a member of the layered transition-metal dichalcogenides with the 1T-CdI-type crystal structure, is known to exhibit a wide variety of magn…
Inter-valence charge transfer and charge transport in the spinel ferrite ferromagnetic semiconductor Ru-doped CoFeO
Masaki Kobayashi, Munetoshi Seki, Masahiro Suzuki +6
Inter-valence charge transfer (IVCT) is electron transfer between two metal sites differing in oxidation states through a bridging ligand: $M^{n+1} + M'^{m} \rightarrow M^{n} +…
On the relationship between orbital moment anisotropy, magnetocrystalline anisotropy, and Dzyaloshinskii-Moriya interaction in W/Co/Pt trilayers
Zhendong Chi, Yong-Chang Lau, Vanessa Li Zhang +15
We have studied the Co layer thickness dependences of magnetocrystalline anisotropy (MCA), Dzyaloshinskii-Moriya interaction (DMI), and orbital moment anisotropy (OMA) in W/Co/Pt t…
