Fe90−xNixZr10 (x= 0, 5, 10, 15, 20 and 25) ribbons with various thicknesses were prepared by
using a melt-spinning technique. The Curie temperature,TC, of the alloys dramatically decreased
from ∼960 K to room temperature at high quenching rates. When the alloys had an amorphous
structure, their TCstrongly depended on the Ni concentration. The maximum entropy change,
|∆Sm|max,with∆H= 12 kOe, of the alloys was around 1 J·kg

at room temperature. On
the other hand, the full width at half maximum the entropy-change peak was quite large,∼85 K,
which was suitable for applications in magnetic refrigerators at room temperature.
