Title: | Magnetocaloric effect and magnetostriction of a binary Nd50Co50 metallic glass | Authors: | Wang, Q Tang, BZ Chan, KC Tang, MB Ding, D Xia, L |
Issue Date: | 1-Nov-2021 | Source: | Journal of non-crystalline solids, 1 Nov. 2021, v. 571, 121076 | Abstract: | The formability and magnetic properties of a low cost Nd50Co50 binary metallic glass were studied in the present work. The Nd50Co50 binary alloy was successfully vitrified into amorphous state with a poor but sufficient formability for glassy ribbon. The Nd50Co50 glassy sample exhibits a spin-glass-like behavior with a Curie temperature of ~ 78 K and a spin freezing temperature of ~ 61 K. The magnetocaloric properties of the Nd50Co50 glassy sample were poor and the mechanism involved was studied. The magnetostriction of the Nd50Co50 glassy sample under 5 T reached to 170 ppm at 30 K, which is not as high as those of Tb(Dy)-based amorphous alloys but much higher than those of TM-based metallic glasses. The binary Nd50Co50 alloy is expected to play a role as basic alloy for developing low-cost multicomponent metallic glasses with outstanding glass formability and magnetostriction. | Keywords: | Magnetic entropy change Magnetostriction Metallic glass Spin glass |
