Effect of site disorder on the electronic, magnetic, and ferroelectric properties of gallium ferrite

Résumé

The electronic, and magnetic properties of the magnetoelectric solid GaFeO 3 are investigated within the generalized gradient approximation including the Hubbard interaction (U) on the localized d orbitals of iron. It was found that using an on-site U =8 eV describes consistently the experimental results. The origin of ferrimagnetism was attributed to the cationic site disorders.
