Controlling Ferromagnetic Easy Axis in a Layered MoS2 Single Crystal

Abstract

We report the effective methods to induce weak ferromagnetism in pristine MoS2 persisting up to room temperature with the improved transport property, which would lead to new spintronics devices. The hydrogenation of MoS2 by heating at 300 C for 1 h leads to the easy axis out of plane, while the irradiation of proton with a dose of 1×1013 P/cm2 leads to the easy axis in plane. The theoretical modeling supports such magnetic easy axes. © 2013 American Physical Society.
