摘要

The new ceramic compounds type BaREBiO4 (where RE = Sm and Nd) have been reported for the first time. The sample was prepared by solid-state reaction technique. The orthorhombic crystallization with a = 6.429(4) angstrom, b = 6.536(5) angstrom, c = 8.648(4) angstrom for BaSmBiO4 and a = 6.485(3) angstrom, b = 6.561(4) angstrom, c = 8.686(4) angstrom for BaNdBiO4 was studied from powder X-ray diffraction studies. The semiconducting nature of the compounds was observed with the energy gap measurement from diffused reflectance spectroscopy (DRS) studies. The paramagnetic nature of the compounds at room temperature and low temperature conditions was identified by magnetization measurements as a function of magnetic fields and temperature. The effective magnetic moment of the samples was found to be 2.126 mu B and 4.272 mu B.
