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…

Transport properties around the metal-insulator transition for SrVO3 ultrathin films fabricated by electrochemical etching

Hikaru Okuma, Yumiko Katayama, Keisuke Otomo +1

By using electrochemical etching, we fabricated conductive ultrathin SrVO3 (SVO) films that exhibited metallic behavior down to 3 monolayers (ML). From an observed systematic chang…

Nonreciprocal magnon propagation in a noncentrosymmetric ferromagnet

Y. Iguchi, S. Uemura, K. Ueno +1

Relativistic spin-orbit interaction drastically modifies electronic band and endows emergent functionalities. One of the example is the Rashba effect. In noncentrosymmetric systems…
