A comprehensive research of the antiferromagnetic(AFM) structures of perovskite-type Eu Zr O3 is carried out by use of the double-time Green’s function.Two possible types of AFM configurations are considered,and theoretical results are compared with experimental results to extract the values of parameters J1,J2,and D.The obtained exchanges are employed to calculate the magnetic susceptibility,which is then in turn compared with the experimental one.Therefore,we think that the magnetic structure of Eu Zr O3 may be an isotropic G-type structure or an anisotropic A-type structure.
