Fig. 4: Calculated magnetic anisotropy energy and electronic band structures as a function of strain.

a Magnetic anisotropy energy (MAE) as a function of in-plane strain by first-principles calculations. The in-plane compressive and tensile strains can increase and decrease MAE, respectively. b Electronic band structures under the compressive and tensile strains. The compressive and tensile strains can push the electron pockets near and away Fermi energy, thereby enhancing and diminishing the MAE of Fe3GaTe2.
