Evolution of anisotropic magnetic properties through helix-to-fan transition in helical antiferromagnetic EuCo2As2

Abstract

Antiferromagnetic systems are prospective materials for spintronic applications due to increased stability and speed of the magnetisation dynamics. Here, the authors use torque magnetometry and an easy-plane anisotropic model to investigate and understand the magnetic anisotropy of the non-collinear antiferromagnet EuCo2As2.
