Low-temperature properties of the t 2g 1 Mott insulators

Low-temperature properties of the t 2g 1 Mott insulators. Interatomic exchange-coupling constants by 2nd-order perturbation theory in t. t 2g 1 + t 2g 1 = t 2g 0 + t 2g 2. Orbital and Magnetic Orders. Superexchange: J AF ~ 4 t 2 /U. t x =t y =99 meV. t x =t y =48 meV.
