Abstract: Gd55Al20Co20Ni5 bulk metallic glass (BMG) was synthesized by minor Ni substitution for Co in the Gd 55Al20Co25 BMG in which excellent glass forming ability (GFA) and magneto-caloric effect were reported previously. The Gd 55Al20Ni20Co5 amorphous rod has a similar GFA to the Gd55Al20Co25 BMG but exhibits better magnetic properties. The peak value of magnetic entropy change (-ΔSm peak) of the Gd55Al 20Co20Ni5 BMG is 9.8 Jkg-1 K -1. The field dependence of -ΔSm peak follows a -ΔSmpeak-H0.85 relationship. The adiabatic temperature rise of the rod is 4.74K under 5 T and is larger than of other BMGs previously reported. The improved magnetic properties were supposed to be induced by the enhanced interaction between 4f electron in the rare-earth and 3d electron in the transition metal elements by means of a minor Ni substitution for Co.
