Circular photogalvanic effect in Cu/Bi bilayers
Hana Hirose, Naoto Ito, Masashi Kawaguchi +2
We have studied the circular photogalvanic effect (CPGE) in Cu/Bi bilayers. When a circularly polarized light in the visible range is irradiated to the bilayer from an oblique inci…
Magnetocrystalline anisotropy and exchange probed by high-field anomalous Hall effect in fully-compensated half-metallic Mn2RuxGa thin films
Ciarán Fowley, Karsten Rode, Yong-Chang Lau +12
Magnetotransport is investigated in thin films of the half-metallic ferrimagnet MnRuGa in pulsed magnetic fields of up to 58 T. A non-vanishing Hall signal is observed over…
Domain wall resistance in CoFeB-based heterostructures with interface Dzyaloshinskii-Moriya interaction
Yuto Ishikuro, Masashi Kawaguchi, Yong-Chang Lau +2
We have studied the domain wall resistance in W/Ta/CoFeB/MgO heterostructures. The Ta layer thickness is varied to control the type of domain walls via changes in the interfacial D…
Current-induced modulation of interfacial Dzyaloshinskii-Moriya interaction
Naoaki Kato, Masashi Kawaguchi, Yong-Chang Lau +3
The Dzyaloshinskii-Moriya (DM) interaction is an antisymmetric exchange interaction that is responsible for the emergence of chiral magnetism. The origin of the DM interaction, how…
Magneto-optic Kerr effect in a spin-polarized zero-moment ferrimagnet
Karsten Fleischer, Naganivetha Thiyagarajah, Yong-Chang Lau +6
The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetisation of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically…
Anomalous spin Hall magnetoresistance in Pt/Co bilayers
Masashi Kawaguchi, Daiki Towa, Yong-Chang Lau +2
We have studied the spin Hall magnetoresistance (SMR), the magnetoresistance within the plane transverse to the current flow, of Pt/Co bilayers. We find that the SMR increases with…
Thermographic measurements of spin-current-induced temperature modulation in metallic bilayers
R. Iguchi, A. Yagmur, Y. -C. Lau +4
Spin-to-heat current conversion effects have been investigated in bilayer films consisting of a paramagnetic metal (PM; Pt, W, or Ta) and a ferromagnetic metal (FM; CoFeB or permal…
