Abstract: Alloys exhibiting table-like magnetic entropy change (-Delta S-m) profiles are regarded as ideal magnetic refrigerants for the Ericsson magnetic refrigeration cycle. In this work, we fabricated two Gd-Co-based amorphous hybrids using various combinations of Gd50Co50, Gd50Co48Fe2, Gd50Co48Mn2 and Gd50Co45Mn5 amorphous ribbons with Curie temperatures ranging from 245 K to 278 K, and obtained table-like -Delta S-m profiles across the ice point of water within different temperature ranges. The maximum -Delta S-m and refrigeration capacity of the amorphous hybrids were higher than those of other amorphous alloys or composites with flattened -Delta S-m values near room temperature, indicating that amorphous hybrids are good candidates for magnetic refrigerants in house-hold magnetic refrigerators.
