Current-in-plane magnetoresistance in chiral-molecule/ferromagnetic metal bilayer due to thermally induced spin polarization
Kouta Kondou, Masanobu Shiga, Shoya Sakamoto +7
We report chirality-induced current-in-plane magnetoresistance (CIP-MR) in chiral molecule/ferromagnetic metal bilayer at room temperature. The previously reported chiralityinduced…
Observation of spontaneous x-ray magnetic circular dichroism in a chiral antiferromagnet
Shoya Sakamoto, Tomoya Higo, Masanobu Shiga +3
X-ray magnetic circular dichroism (XMCD) signals are usually absent in antiferromagnets. In this letter, we report the observation of spontaneous XMCD spectra originating from the…
Magnetic anisotropy of the van der Waals ferromagnet CrGeTe studied by angular-dependent XMCD
M. Suzuki, B. Gao, G. Shibata +12
The van der Waals ferromagnet CrGeTe (CGT) has a two-dimensional crystal structure where each layer is stacked through van der Waals force. We have investigated the nat…
Chirality-induced effective magnetic field in a phthalocyanine molecule
Shinji Miwa, Kouta Kondou, Shoya Sakamoto +4
Chirality in organic molecules has attracted considerable attention in the fields of chemistry, biology, and spintronics. This paper reports on perpendicular magnetization hysteres…
Giant effective damping of octupole oscillation in an antiferromagnetic Weyl semimetal
Shinji Miwa, Satoshi Iihama, Takuya Nomoto +8
A magnetic Weyl semimetal is a recent focus of extensive research as it may exhibit large and robust transport phenomena associated with topologically protected Weyl points in mome…
Connection between coherent phonons and electron-phonon coupling in Sb (111)
Shoya Sakamoto, Nicolas Gauthier, Patrick S. Kirchmann +2
We report time- and angle-resolved photoemission spectroscopy measurements on the Sb(111) surface. We observe band- and momentum-dependent binding-energy oscillations in the bulk a…
Development of magnetism in Fe-doped magnetic semiconductors: Resonant photoemission and x-ray magnetic circular dichroism studies of (Ga,Fe)As
Takahito Takeda, Shoya Sakamoto, Le Duc Anh +8
Fe-doped III-V ferromagnetic semiconductors (FMSs) such as (In,Fe)As, (Ga,Fe)Sb, (In,Fe)Sb, and (Al,Fe)Sb are promising materials for spintronic device applications because of the…
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…
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…
