A study of the spin reorientation with t–e orbital hybridization in SmCrO3

We present an experimental and computational study of SmCrO3 on the spin-reorientation transitions and spin orbital structures in the two different phase configurations. The experimental results reveal distinct spin reorientation transitions under different external fields. First-principles density functional theory calculations perform the existence of t–e orbital hybridization and the structure distortion during the phase transitions process. The spin reorientation transition was potentially driven by the correlated exchange splitting and the t–e orbital hybridization between Cr3+ and Cr3+ ions.
