Abstract
The effects of strain on the ordered L10 and L12 phases of PtxNi1−x (x=0.25, 0.5, and 0.75) have been investigated using both scalar and vector relativistic density functional theory (DFT). The spin orbit correction (SOC) orders the local magnetic moment vector along ΓR (ΓA) diagonal of the L12 (L10) phases. Applying tensile (compressive) strain to each phase causes the local magnetic moment of the crystal to increase (decrease). The SOC component of the local magnetic moment is independent of the stress applied to the crystal.
