Abstract

We investigate the magnetic interactions in Sr3NiPtO6, characterized to be a spin liquid using ab initio calculations. The results reveal a novel metal to insulator transition due to finite exchange interaction strength; the magnetic solutions (independent of magnetic ordering) are large band gap insulators, while the non-magnetic solution is metallic. The Ni moment is found to be large and the coupling among intra-chain Ni moments is antiferromagnetic unlike other compounds in this family. These results, thus, reveal the importance of intra-chain antiferromagnetic interaction in addition to geometrical frustration to derive spin liquid phase.
