Abstract A Fe87Zr7B4Co2 amorphous alloy with excellent magneto-caloric effect near room temperature was fabricated in the present work. The amorphous alloy exhibits typical soft magnetic behavior with nearly zero coercivity at a sub-ambient temperature. The glassy ribbon presents a rather high peak value of magnetic entropy change and refrigeration capacity near room temperature compared to other Fe-based amorphous alloys, indicating that the amorphous alloy is a good component of magnetic refrigerants near the hot end of a magnetic air conditioner.

Fe 87 Zr 7 B 4 Co 2 非晶合金，在室温附近具有优异的磁热效应

摘要 本工作制备了一种在室温附近具有优异磁热效应的Fe87Zr7B4Co2非晶合金。非晶合金在低于环境温度下表现出典型的软磁行为，矫顽力几乎为零。与其他铁基非晶合金相比，玻璃带在室温附近呈现出较高的磁熵变和制冷能力峰值，表明非晶合金是磁空调热端附近磁性制冷剂的良好成分。
