Abstract

We investigate the electronic structure of Sr3NiPtO6 using ab initio calculations. This compound is a geometrically frustrated insulator and does not show long-range order down to 1.8 K measured; a signature of spin-liquid-like behavior. Electronic band structure calculation within the local spin density approximations in our study reveals an insulating ground state in Sr3NiPtO6 unlike analogous compounds in this family. The Ni moment is found to be large and the intra-chain coupling favors antiferromagnetic ordering. These results establish the importance of intra-chain antiferromagnetic interaction in addition to geometrical frustration to derive the ground-state properties.
