The electronic and magnetic properties of LaOFePn (Pn = P, As and Sb) have been investigated by employing first-principles density functional theory. The results show that LaOFeSb has similar properties with LaOFeAs and LaOFeP In this kind of Fe-based layer superconductivity, the arrangement of Fe spins is determined by the superexchange and direct exchange collectively.
