Tuning the hysteresis loop for the anomalous Hall effect in Pt ultrathin films on by electrolyte gating
Leon Sakakibara, Yumiko Katayama, Tomohiro Koyama +2
Pt ultrathin films on ferromagnetic insulators have been widely studied for spintronics applications, and magnetic moments of interface Pt atoms were considered to be ferromagnetic…
Giant gate-controlled proximity magnetoresistance in semiconductor-based ferromagnetic/nonmagnetic bilayers
Kosuke Takiguchi, Le Duc Anh, Takahiro Chiba +3
The evolution of information technology has been driven by the discovery of new forms of large magnetoresistance (MR), such as giant magnetoresistance (GMR) and tunnelling magnetor…
Large current modulation and tunneling magnetoresistance change by a side-gate electric field in a GaMnAs-based vertical spin metal-oxide-semiconductor field-effect transistor
Toshiki Kanaki, Hiroki Yamasaki, Tomohiro Koyama +3
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…
Microscopic origin of electric-field-induced modulation of Curie temperature in cobalt
Fuyuki Ando, Kihiro T. Yamada, Tomohiro Koyama +5
The Curie temperature is one of the most fundamental physical properties of ferromagnetic materials and can be described by Weiss molecular field theory with the exchange interacti…
Origin of threshold current density for asymmetric magnetoresistance in Pt/Py bilayers
Tian Li, Sanghoon Kim, Seung-Jae Lee +7
An asymmetric magnetoresistance (MR) is investigated in Py/Pt bilayers. The asymmetric MR linearly increases with current density up to a threshold, and increases more rapidly abov…
Microscopic Origin of Interfacial Dzyaloshinskii-Moriya Interaction
Sanghoon Kim, Kohei Ueda, Gyungchoon Go +15
Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of the…
