## Description

- description: The current-induced spin-orbit torque-based devices for magnetization
    switching commonly relied on the 4d and 5d heavy metals owing to their strong
    spin-orbit coupling (SOC) to produce large spin current via spin Hall effect (SHE).
    Here we present the sizable SHE in CrN, a light element-based system, and demonstrate
    the current-induced magnetization switching in the adjacent ferromagnetic layer
    [Co(0.35nm)/Pt(0.3nm)]3, which exhibits perpendicular magnetic anisotropy. We
    found the switching current density of 2.6MA/cm2.The first principles calculation
    gives the spin Hall conductivity (SHC) ∼ 120 S/cm due to intrinsic spin Berry
    curvature arising from SOC induced band splitting near Fermi energy. The theoretically
    calculated intrinsic SHC is close to the experimental SHC extracted from second
    harmonic Hall measurement. We estimated spin Hall angle (θSH) ∼0.09, demonstrating
    efficient charge-to-spin conversion in CrN system.
