چکیده انگلیسی
Alloys exhibiting table-like magnetic entropy change (âÎSm) 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 âÎSm profiles across the ice point of water within different temperature ranges. The maximum âÎSm and refrigeration capacity of the amorphous hybrids were higher than those of other amorphous alloys or composites with flattened âÎSm values near room temperature, indicating that amorphous hybrids are good candidates for magnetic refrigerants in house-hold magnetic refrigerators.
