Abstract:

Effect of rapid quenching on the magnetic state and magnetocaloric properties of the Gd3Co and Gd3Ni intermetallic compounds has been studied. The rapidly quenched Gd75Co25 and Gd75Ni25 alloys were found to exhibit a ferromagnetic behavior below the Curie temperature (C) = 172 and 117 K, respectively, whereas their crystalline counterparts Gd3Co and Gd3Ni are characterized by an antiferromagnetic order and N,el temperatures (N) = 130 and 99 K, respectively. Data have been obtained which indicate that the amorphization of Gd3Co leads to the appearance of a magnetic moment at cobalt atoms. The rapid quenching is shown to lead to a significant increase in the low-field magnetocaloric effect.
