Magnetic and transport properties of Gd3Y4Pd3 single crystal

Electronic structure, temperature dependences of the lattice parameters and magnetic properties of a crystal belonging to the series Gd7−xYxPd3 has been measured. Gd3Y4Pd3 orders ferromagnetically at 197 K and all measured physical properties show a strong anisotropy. The saturation magnetic moment per Gd ion is enhanced in relation to the theoretical value. The investigations of the magnetocaloric properties of the Gd3Y4Pd3 using the magnetization measurements have been performed in the temperature range of 2-300 K and magnetic field range of 0-7 T. The calculated values of entropy change ΔSm for examined compound amount −3.81 J/K kg for a axis and −3.97 for c axis at 7 T.
