- Abstract
Mn2PtSn tetragonal is promising for spintronic devices, especially for spin-transfer-torque based devices. We apply the density functional theory formalism to make a detailed study of the structural, magnetic, and electronic properties for Mn2PtSn crystals. The dependence of the elastic constants Cij for cubic and tetragonal structure, the aggregate elastic moduli B, G, and the anisotropy A, along with the related mechanical properties are investigated. The Curie temperatures and the magnetic moments in both the cubic as well as tetragonal phases have been calculated. Mn2PtSn can be studied in inverse tetragonal crystal structure with antiferromagnetic spin order. Because of the high magnetic anisotropy, low magnetization, and high spin polarization at the Fermi level, this material is expected to be promising for spin-transfer-torque applications.
