- •
Hydrogen was introduced to the Fe90M10 (M: Zr and Sc) amorphous refrigerant materials.
- •
Hydrogen introduction significantly enhanced peak magnetic entropy change of the alloys.
- •
Hydrogen introduction tuned Curie temperature to room temperature.
- •
The refrigerant capacity of the hydrogenated alloy exhibits a large value of 216.2 J/kg.
- •
The underlying mechanism is revealed.
