Abstract

The volume compression of BaNd2CuO5 has been measured to 8.7 GPa utilizing a diamond anvil high pressure eel and energy dispersive x-ray powder diffraction. The pressure dependence of the volume of the tetragonal unit cell is linear and follows the equation V = -1.6I5P + 260.622 determined by a least-squares fit of the data. Compression of the unit cell parameters of BaNd2CuO5 exhibit isotropic behavior within our experimental error. From the observed data, the bulk modulus of BaNd2CuO5 is determined to be 161 ± 6 GPa and the Young's modulus is estimated to be 193 ± 6 GPa. No evidence of a pressure-induced phase transformation in BaNd2CuO5 was found in the pressure range studied.
