We investigated the biaxial strain dependent magnetic properties of two dimensional (2D) VSe₂ single layer using the density functional theory. The ferromagnetic state of the pristine VSe₂ monolayer was preserved under the applied strain. Also, the pristine VSe₂ monolayer had an in-lane magnetic anisotropy of -0.47 meV/cell. The in-plane anisotropy was maintained in both tensile and compressive strain. However, the magnitude of magnetic anisotropy was dependent on the strain type. For instance, the in-plane magnetic anisotropy decreased under compressive strain whereas the opposite behavior appeared under tensile strain. We also explored the strain dependent Curie temperature. The pristine structure had a Curie temperature (TC) of ~ 237K. By applying strains, the exchange energy was enhanced and subsequently, the TC was increased as well. Particularly, we found that the TC increased to 323 K under the tensile strain of 3%. Our finding illustrates the role of the strain in achieving tunable magnetic properties for potential spintronics and straintronics applications in the 2D 1T-VSe₂.
