Abstract
Partial Nd-substitution effects on the magnetic and magnetocaloric properties in spin-reorientation Pr1−x Nd x Co4Al (x = 0, 0.2, 0.4, 0.6, 0.8) alloys are investigated. All these alloys undergo two successive spin-reorientation transitions. Accordingly, the successive positive and negative magnetic entropy changes (Δ S M ) for all these alloys are obtained. With the increase of Nd content, the spin reorientation transition temperatures increase from about 170 and 186 K for x = 0 to room temperature (276 and 294 K) for x = 0.8, covering a wide temperature interval. More interestingly, the values of positive Δ S M values increase gradually from 0.1 to 0.9 J/kg K−1, while the negative Δ S M decrease from 1.3 to 0.2 J/kg K−1 in the field change of 10 kOe. In addition, the series has an appreciable relative cooling power, which is therefore suitable to be used in a magnetic refrigerator.
