(Color online) Tetragonal structure - alternating Fe and Pt atomic planes with square lattice along (001) direction.

(Color online) MAE as a function of in-plane biaxial strain. MAE reduces with positive value of (tensile strain). Inset: and c/a as a function of an in-plane biaxial strain.

FIG. 3.

MAE as function of the ratio of lattice parameters c/a at fixed cell volume corresponding to experimental data. MAE reduces by about 20% at 3% c/a reduction.
