Density functional theory and generalized gradient approximation (GGA) with onsite Coulomb interaction (GGA+U) is used to calculate the magnetic properties of new material La2CoZrO6. Here, we considered the possibilities of four magnetic orderings: ferromagnetic, ferrimagnetic, antiferromagnetic, and nonmagnetic states. Under the GGA+U scheme, we finally find that the antiferromagnetic insulator stands out as the most stable state among these four states.
