Effect of Pressure on the Fermi Surface of ReO3

Abstract
We have determined the pressure derivatives of several cross-sectional areas of the Fermi surface of ReO3 as well as the isothermal compressibility at room temperature. The cross-sectional areas increase at rates of (1.5-4.0)×104 kbar1 compared to the free-electron scaling prediction of 3.6×104 kbar1.
