Abstract This study investigates the effect of strain on the compensation temperature of ferrimagnetic Tb–Fe films formed on a flexible substrate. The compensation temperature is determined by the anomalous Hall measurement, and an application of 1

Abstract A vertical spin metal-oxide-semiconductor field-effect transistor (spin MOSFET) is a promising low-power device for the post scaling era. Here, using a ferromagnetic-semiconductor GaMnAs-based vertical spin MOSFET with a GaAs channel layer,

Dzyaloshinskii–Moriya interaction (DMI) is one of the key factors to control the chiral spin textures in spintronic applications. Here the authors demonstrate the correlation of the DMI with the anisotropy of the orbital magnetic moment and magneti

Abstract Manipulation of magnetization using current-induced torque is crucial for magnetic recording devices. Recently, the spin-orbit torque (SOT) that emerges in a ferromagnetic thin film on a heavy metal is focused as a new scheme for magnetizati

The electric field effect on the magnetism in a MgO/Pd/Co system, in which a magnetic moment is induced in the Pd layer owing to the ferromagnetic proximity effect, has been investigated using various experimental methods. An electric field was appli

The authors have investigated magnetic domain wall (DW) motion induced by electrical current in the perpendicularly magnetized Pt/Co/Pd and Pd/Co/Pt structures. In these systems, owing to the spin-orbit torque (SOT) and the interfacial Dzyaloshinskii

We investigate current-induced spin-orbit torque (SOT) in Co/Pt/oxide systems by varying a sort of the oxide layer. When the Pt thickness is less than \ensuremath{\sim}2 nm, Pt at the interface of the oxide layer is magnetically polarized owing to th

We demonstrate that magnetic crystal anisotropy ( K u ) and spectroscopic g-factor can be modulated simultaneously by gate voltage in a Pt/Co/MgO ultrathin film with our ferromagnetic resonance (FMR) measurement based on the rectification effect. The

The evolution of information technology has been driven by the discovery of new forms of large magnetoresistance, such as giant magnetoresistance1,2 and tunnelling magnetoresistance3,4, in magnetic multilayers. Recently, new types of this effect have
