【Abstract】 Alloys GdCo 2 and Gd 6Fe 23 were obtained by melting corresponding metals in argon atmosphere. The magnetization curves of these alloys were measured with vibration sample magnetometer, from which magnetic entropy changes were calculated and magnetocaloric effect were evaluated. This work provides preliminary information needed for the design of magnetic refrigerators.更多还原
