Abstract
- In this study, we present the crystal structure, magnetic properties, and cryogenic magneto-caloric effect (MCE) of RE 2 FeAlO 6 (RE = Gd, Dy, Ho) oxides. The XRD refinement analysis suggests that all the RE 2 FeAlO 6 oxides are crystallized in B-site disordered orthorhombic structure. The RE 2 FeAlO 6 oxides exhibit large MCEs around T C. The peak magnetic entropy change (-Δ S M) and refrigeration capacity (RC) are 25.9 J/(kgK) and 240.1 J/kg for Gd 2 FeAlO 6 , 10.7 J/(kgK) and 274.9 J/kg for Dy 2 FeAlO 6 , 9.6 J/(kgK) and 249.6 J/kg for Ho 2 FeAlO 6 under Δ H of 0–70 kOe, respectively. Notably, Gd 2 FeAlO 6 exhibits promising magneto-caloric performance and therefore is a favorable candidate for cryogenic magnetic refrigeration. [ABSTRACT FROM AUTHOR]
