A First-Principles Study of a New Heusler Alloy

Abstract:

We studied a new Heusler alloy V₂CoSi with Hg₂CuTi-type structure by first-principles calculations. The electric structure and magnetic properties have been investigated. The alloy has a total magnetic moment of 1.00μ_B per unit cell on first-principles calculations which is in agreement with the SlaterPauling (SP) rule. The magnetic moment of atom Co is 0.38μ_B and the magnetic moments of V(1) atom and V(2) atom are 0.80μ_B and-0.24μ_B respectively, so the alloy is a ferrimagnetism.
