First-Principles Study of Induced Magnetism in Tungsten Vanadium Selenide Alloys for Spintronic Applications.

ABSTRACT: The possibility of inducing magnetization in tungsten selenide monolayer by alloying with vanadium selenide was investigated through first-principles calculations. Electronic, optical, and magnetic properties of different W_1-x V _x Se₂ alloy compositions were studied extensively. As the proportion of vanadium atoms in the alloys increased, a phase transition from semiconducting to metallic to semiconducting was discovered. All alloy compositions demonstrated induced magnetism with a long-range ferromagnetic order. Interestingly, in the case of the W_0.25V_0.75Se₂ alloy, spin-up states in the band diagram showed a finite band gap, while a nonzero band gap was found for spin-down states. The W_0.25V_0.
