摘要：
We report density functional calculations addressing the electronic structure and magnetic properties of delafossite PdCrO2. We find substantial magnetic interactions in the c-axis direction as well as beyond first nearest neighbors in-plane, so that PdCrO2 is a three-dimensional (3D) frustrated antiferromagnet. We also find substantial coupling between the Cr moments and the Pd derived conduction electrons.
