(a) Schematic representation of crystal structure. Gd atoms (blue spheres) occupy the cube corner positions (0,0,0). The face center positions are occupied by Pd atoms (black spheres) and the body center position is occupied by either B (red spheres) or C (green spheres). Eight corner sharing octahedra surrounding central Gd atom in (b) and in (c) .
Lattice parameter (a) of as a function of temperature. The solid line is guide to eye. Error bars have been doubled for better visibility. The layers 1 and 2 in inset (a) show the XRD pattern of taken at and , respectively, while the layers 3 and 4 show the same for . Inset (b) shows the lattice parameter of as a function of temperature. The error bars equal the size of the symbols.
Resistivity ratio as a function of temperature. Inset shows in a restricted temperature range for magnetic fields and .
Variation of dc-magnetization (left axis) and inverse molar susceptibility (right axis) with temperature. Inset shows isothermal magnetization as a function of applied field.
