摘要/Abstract

摘要： A comprehensive research of the antiferromagnetic (AFM) structures of perovskite-type EuZrO₃ 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 EuZrO₃ may be an isotropic G-type structure or an anisotropic A-type structure.

关键词: quantized spin model, quantum phase transition, europium titanate
