Abstract

A new high-pressure polymorph of CrSb2 was synthesized under high-pressure/temperature conditions of 7-7.7 GPa and 600-650 °C. The crystal structure is body-centered tetragonal with the space group I4/mcm, which is assigned to CuAl2-type structure. The experiments under various pressure conditions revealed that the high-pressure polymorph was formed above 5.5 GPa, and the compound crystallized into the low-pressure marcasite-type structure below 5 GPa. The characteristic of the high-pressure phase is the metallic bond nature including the formation of Cr-Cr-Cr linear chain along the c-axis. The compound shows metallic conductivity and itinerant-electron ferromagnetic behavior with the Curie temperature of ca. 160 K.
