Magnetism and transport studies in off-stoichiometric metallic perovskite compounds GdPd3Bx (x=0.25, 0.50 and 0.75)

We report the magnetic and transport properties of the off-stoichiometric metallic perovskite like compounds GdPd3Bx (x=0.25, 0.50 and 0.75). Our results show that doping with boron in the lattice of parent binary-compound GdPd3 leads to lattice expansion. Which in turn manifests in contrasting magnetic and transport behaviors of the doped compounds in comparison with the undoped GdPd3. An attempt has been made to compare and correlate the results of magnetic and transport measurements of GdPd3Bx with that of stoichiometric compositions GdPd3BxC1−x. The comparative study of GdPd3Bx and GdPd3BxC1−x confirms that there is a strong correlations between the structural, magnetic and transport properties of these compounds.
