          Abstract

          We identify ground-state collinear spin ordering in various antiferromagnetic transition metal oxides by constructing the Ising model from first-principles results and applying a genetic algorithm to find its minimum energy state. The present method can correctly reproduce the ground state of well-known antiferromagnetic oxides such as NiO, Fe 2O 3, Cr 2O 3 and MnO 2. Furthermore, we identify the ground-state spin ordering in more complicated materials such as Mn 3O 4 and CoCr 2O 4.
