Abstract:
Rapid quenching and ball milling have been used to modify the magnetic state and magnetocaloric properties of the intermetallic compound Gd3Ni. The melt-spun and ball-milled Gd3Ni samples are found to exhibit a soft ferromagnetic-like behavior below 120 K, whereas in the crystalline state, the Gd3Ni compound is an antiferromagnet with a Neel temperature of about 99 K. The reduced value of the saturation magnetization observed in amorphous Gd3Ni samples is ascribed to the appearance of a magnetic moment on Ni atoms. After amorphization, the Gd3Ni samples exhibit substantially improved magnetocaloric properties in a low field region in comparison with crystalline Gd3Ni.
