Anomalous Hall Effect in Epitaxial Thin Films of Mn_2VAl Full-Heusler Alloy

摘要

Mn-based full-Heusler ferrimagnet, Mn_2VAl is a promising source for spin injection because of its high spin polarization and low magnetization, however, the magneto-transport properties of the thin films have scarcely been reported. Mn_2VAl may exhibit specific behavior in anomalous Hall effect (AHE) as compared to well-studied Co-based Heusler alloys because the DOS in spin-down electrons for Mn_2VAl consists of the d orbital band at the Fermi level. In this study, AHE in epitaxial thin films of Mn_2VAl was investigated.
