Averievite: A copper oxide kagome antiferromagnet

Journal Article · · Physical Review B
Averievite, Cu5V2O10(CsCl), is an oxide mineral composed of Cu2+ kagome layers sandwiched by Cu2+-V5+ honeycomb layers. We have synthesized this oxide and investigated its properties from ab initio calculations along with susceptibility and specific heat measurements. The data imply a Curie-Weiss temperature of 185K as well as long-range magnetic order at 24 K due to the significant interlayer coupling from the honeycomb copper ions. This order is suppressed by substituting copper by isoelectronic zinc, suggesting that Zn-substituted averievite is a promising spin liquid candidate. A further proposed substitution that replaces V5+ by Ti4+ not only dopes the material but is predicted to give rise to a two-dimensional electronic structure featuring Dirac crossings. Thus, averievite is an attractive platform for S =1/2 kagome physics with the potential for realizing novel electronic states.
