Anomalous Hall Effect and Perpendicular Magnetic Anisotropy in Ultrathin Ferrimagnetic NiCo${}_2$O${}_4$ Films

Xuegang Chen, Qiuchen Wu, Le Zhang +4

The inverse spinel ferrimagnetic NiCo${}_2$O${}_4$ possesses high magnetic Curie temperature $T_C$, high spin polarization, and strain-tunable magnetic anisotropy. Understanding the th…
