Tuning the hysteresis loop for the anomalous Hall effect in Pt ultrathin films on $\mathrm{CoF}{\mathrm{e}}_2{\mathrm{O}}_4$ 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…
