Effect of crystallinity on spin-orbit torque in 5 iridium oxide IrO
Tetsuro Morimoto, Kohei Ueda, Junichi Shiogai +3
The 5 transition-metal oxides provide an intriguing platform for generating an efficient spin current due to a unique electronic structure dominated by 5d electrons wit…
Effect of interface quality on spin Hall magnetoresistance in Pt/MgFeO bilayers
Masafumi Sugino, Kohei Ueda, Takanori Kida +2
We report on spin Hall magnetoresistance (SMR) in bilayers composed of Pt and magnetic insulator MgFeO (MFO) with spinel structure. The Pt thickness dependence of the S…
NiCrAl piston-cylinder cell for magnetic susceptibility measurements under high pressures in pulsed high magnetic fields
Katsuki Nihongi, Takanori Kida, Yasuo Narumi +5
We developed a metallic pressure cell made of nickel-chromium-aluminum (NiCrAl) for use with a non-destructive pulse magnet and a magnetic susceptibility measurement apparatus with…
Spin current generation from an epitaxial tungsten dioxide WO
Kohei Ueda, Hayato Fujii, Takanori Kida +2
We report on efficient spin current generation at room temperature in rutile type WO grown on AlO(0001) substrate. The optimal WO film has (010)-oriented mo…
Spin Hall magnetoresistance in Pt/YFeO bilayers grown on Si and GdGaO substrates
Kenta Fukushima, Kohei Ueda, Naoki Moriuchi +3
We study spin Hall magnetoresistance (SMR) in Pt/ferrimagnetic insulator YFeO (YIG) bilayers by focusing on crystallinity, magnetization, and interface roughness…
Spin-orbit torque generation in bilayers composed of CoFeB and epitaxial SrIrO grown on an orthorhombic DyScO substrate
Sosuke Hori, Kohei Ueda, Takanori Kida +2
We report on the highly efficient spin-orbit torque (SOT) generation in epitaxial SrIrO(SIO), which is grown on an orthorhombic DyScO(110) substrate. By conducting harm…
