Pressure dependent half-metallic ferromagnetism in inverse Heusler alloy FeCoAl: a DFT+U calculations.

We report the electronic and magnetic properties along with the Curie temperature ( ) of the inverse full Heusler alloy (HA) FeCoAl obtained by using the first-principles computational method. Our calculations suggests that FeCoAl is a magnetic metal when treated within PBE-GGA under the applied compressive pressures. However, the implementation of electron-electron (U) (, GGA+U) with varying compressive pressure () drastically changes the profile of the electronic structure.
