Abstract
The influences of gallium substitution for terbium in Gd60Tb40 on the phase formation, Curie temperature and magnetic entropy change have been investigated. A series of Gd60Tb40−xGax with x=0, 1, 3 and 5 alloys were prepared by arc-melting method. The X-ray diffraction (XRD) analysis reveals that a small amount of Ga substitution for terbium in Gd60Tb40 can form the solid solution (Gd, Tb). The Curie temperature (Tc) increases from 270 K for Gd60Tb40 to 297 K for Gd60Tb37Ga3, while the maximum magnetic entropy changes ΔSM, max decreases from 5.15 J/K kg for Gd60Tb40 to 3.32 J/K kg for Gd60Tb37Ga3 with increasing the Ga content.
