Abstract
Electronic structure, transport and magnetic properties of the Gd 6YPd 3 single crystal have been measured. This compound crystallizes in the hexagonal Th 7Fe 3 type of structure with the ratio c/ a = 0.63 similar to that obtained for Gd 7Pd 3. Gd 6YPd 3 orders ferromagnetically at 299 K while Gd 7Pd 3 displays also ferromagnetic transition but at about 334 K. All measured physical properties show a strong anisotropy. The thermal dependence of the electrical resistivity shows an anomalous character having a strong negative curvature and quadratic temperature dependences at low temperatures. The saturation magnetic moment per Gd ion is enhanced in relation to the theoretical value. Spin fluctuations taking place on the palladium atoms may be responsible for the magnetic properties of ternary compound.
