Nonlinear Structural and Magnetic Transition in Co-doped Fe2VGa Heusler Alloy

摘要：

　　By using local spin density approximation (LSDA) scheme within the density functional theory (DFT),the structural,magnetic and electronic properties of Heusler alloy Fe2V1-xCoxGa were comprehensively investigated.The results reveal that with the increase of Co-doped concentration,in Fe2V1-xCoxGa alloy,a nonmagnetic-ferromagnetic transition appears,and the nonlinearly structural and magnetic variation respectively against the linear Vegard law and Slater-Pauling rule are also detected.Further analysis of electronic structure reveals that both contributions from Fe-Co and Fe-V magnetic interaction in Fe2V1-xCoxGa alloy play a dominating role in determining the nonlinear magnetic and electronic behaviors.
