- •
Minor Si addition enhances the −ΔSmpeak but decreases the Tc of the Gd50Co50 metallic glass significantly.
- •
The Gd50Co50−xSix (x=2, 5) as-spun ribbons exhibit typical magneto-caloric behaviors of soft magnetic metallic glasses.
- •
A nearly linear dependence of ln(−ΔSmpeak) on the ln(Tc−2/3) in Gd-Co-based amorphous ribbons was found.
