Abnormal peak of angular-dependent Hall effect as an indicator for skyrmion in perpendicular magnetic anisotropy system
J Tang, G Xu, Y You, Z Xu, Z Zhang, X Chen… - Applied Physics …, 2020 - pubs.aip.org
The anomalous Hall effect (AHE) has been extensively studied in terms of its diverse and
profound physics, but the AHE behavior under spatially rotated external fields has not been
well understood yet. Here, we selected a traditional CoFeB-based multilayer film as the
platform, and by continuously tuning its magnetic anisotropy, we have observed the
progressively evolved angular-dependence of the AHE, in which an abnormal turning peak
emerged in the case of moderate perpendicular magnetic anisotropy (PMA). By applying …
