Abstract

$YCrO_{3}$, which has a monoclinic structure, shows weak ferromagnetism below 140 K $(T_{N})$ and a ferroelectric transition at 473 K accompanied by hysteresis. We have determined the structure and energetics of $YCrO_{3}$ with ferromagnetic and antiferromagnetic ordering by means of first-principles density functional theory calculations, based on pseudopotentials and a plane-wave basis. The noncentrosymmetric monoclinic structure is found to be lower in energy than the orthorhombic structure, supporting the biferroic nature of $YCrO_{3}$.
