Heterostructure engineering for wurtzite LaN

The Journal of Chemical Physics
Wurtzite LaN (wz-LaN) is a semiconducting nitride with favorable piezoelectric and ferroelectric properties, making it promising for applications in electronics. We use first-principles density functional theory with a hybrid functional to investigate several features that are key for its use in heterostructures.

Microstructural evolution and enhanced spin-orbit torque in Pt-Zr alloyed magnetic heterostructures

Materials & Design
Platinum (Pt) holds great promise for generating spin–orbit torque (SOT) due to its large spin Hall conductivity and low resistivity. Like Pt/Co, Pt-based magnetic heterostructures exhibit perpendicular magnetic anisotropy (PMA).
