This paper presents, we present the structure, magnetic properties, and magnetocaloric effect of the Fe81-xCrx+4B2Zr10Nd3 (x = 0, 1, 2, and 3) alloy ribbons. The alloy ribbons were prepared by using the melt-spinning method. Structural analysis by X-ray diffraction shows that the obtained alloy ribbons are almost amorphous. Curie temperature of the alloy ribbons decreases from 310 to 275 K when x increases from 0 to 3. Under a magnetic field change of 12 kOe, the maximum magnetic entropy change (|DSm|max) of the Fe80Cr5B2Zr10Nd3 alloy ribbon is found to be 1.05 J.kg-1.K-1 at 302 K. In addition, the large refrigerant capacity (RC >
80 J∙kg-1 with DH = 12 kOe) at room temperature is obtained in the alloy ribbon. Thus, the alloy ribbons can be considered a potential magnetic refrigerant in the room temperature range.
