Strongly correlated antiferromagnetic vanadates

Abstract

Antiferromagnetic (AFM) materials have zero net magnetic moments due to the alignment of adjacent magnetic moments antiparallel to each other, which have drawn extensive interest in the field of next generation spintronics, thanks to the merits of negligible stray fields, fast spin dynamics, and robustness against magnetic disturbances. In the past decades, the strongly correlated vanadates of VO2, V2O3, and RVO3 have extensively been studied because of noteworthy metal–insulator transitions. Nevertheless, the magnetism (especially antiferromagnetism) in the vanadates has attracted less attention. This Perspective provides a brief overview of the strongly correlated AFM vanadates. First, an introduction to the basic concept of antiferromagnetism and vanadates is presented. Then, the antiferromagnetism in vanadates containing V4+ (VO2, NaV2O5, and Sr2VO4), V3+ (V2O3, RVO3, AV2O4, and VOCl), and V2+ (VO) with different spin moments is presented. Finally, a summary and outlook with respect to the antiferromagnetism in vanadates are included.
