Abstract

The 5M BaIrO₃, which is intervenient in the 9M and 6M forms, was synthesized under high pressure and high temperature, and the physical properties were obtained. The measurement of low-temperature electrical resistivity shows that the 5M BaIrO₃is a Fermi-Liquid metal, because of the linear relationship of ρ versus T² at low temperature. The relationships of magnetic susceptibility versus temperature indicate that the 5M BaIrO₃ is a weak ferromagnet, with the Curie temperature T_c about 54.3 K. According to the Wilson ratio R_W of 1.67(4) and Stoner enhancement factor S of 2.8 calculated through the low-temperature specific heat data, there is a modest electron-electron correlation effect in the 5M BaIrO₃.
