Direct observation of oxygen polarization in SrIrO by O -edge x-ray magnetic circular dichroism
R. Kadono, M. Miyazaki, M. Hiraishi +4
X-ray absorption spectroscopy (XAS) and magnetic circular dichroism (XMCD) measurements at the oxygen (O) -edge were performed to investigate the magnetic polarization of ligand…
The origin of enhanced interfacial perpendicular magnetic anisotropy in LiF-inserted Fe/MgO interface
Shoya Sakamoto, Takayuki Nozaki, Shinji Yuasa +2
The Fe/MgO interface is an essential ingredient in spintronics as it shows giant tunneling magnetoresistance and strong perpendicular magnetic anisotropy (PMA). A recent study demo…
Development of a versatile micro-focused angle-resolved photoemission spectroscopy system with Kirkpatrick-Baez mirror optics
Miho Kitamura, Seigo Souma, Asuka Honma +11
Angle-resolved photoemission spectroscopy using a micro-focused beam spot (micro-ARPES) is becoming a powerful tool to elucidate key electronic states of exotic quantum materials.…
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…
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…
Relationship between charge redistribution and ferromagnetism at the heterointerface between perovskite oxides LaNiO and LaMnO
Miho Kitamura, Masaki Kobayashi, Enju Sakai +10
To investigate the relationship between the charge redistribution and ferromagnetism at the heterointerface between perovskite transition-metal oxides LaNiO (LNO) and LaMnO…
Element-specific soft X-ray spectroscopy, scattering and imaging studies of skyrmion-hosting compound CoZnMn
V. Ukleev, Y. Yamasaki, D. Morikawa +10
A room-temperature skyrmion-hosting compound CoZnMn has been examined by means of soft X-ray absorption spectroscopy, resonant small-angle scattering and extended refer…
Effect(s) of Cobalt Substitution in -(Fe,Co)Pt Thin Films
Shoya Sakamoto, Kumar Srinivasan, Rui Zhang +9
We have studied the effect of cobalt substitution in -FeCoPt films by means of x-ray magnetic circular dichroism (XMCD) and first-principles calculations. The…
Observation of Magnetic Edge State and Dangling Bond State on Nanographene in Activated Carbon Fibers
Manabu Kiguchi, Kazuyuki Takai, V. L. Joseph Joly +3
The electronic structure of nanographene in pristine and fluorinated activated carbon fibers (ACFs) have been investigated with near-edge x-ray absorption fine structure (NEXAFS) a…
