Polycrystalline samples of Y1-xGdxBa2Cu3O7 with different Gd contents (x = 1, 0.75, 0.5, 0.25) were prepared using the usual solid state reaction method. X-ray characterization of these samples showed an orthorhombic phase. The lattice parameters a, b, and c were found to increase with increasing Gd concentration which is due to the larger volume of Gd atoms. Magnetization and transport measurements show the same transition temperature of 91 K for all samples studied. Initial and magnetization hysteresis loop measurements showed that the paramagnetic behavior is dominant at high fields.
