“…Inverse and direct magnetocaloric properties were also observed by Ma et al [31] in melt-spun and annealed Ni 42.7 Mn 40.8 Co 5.2 Sn 11.3 ribbons. The maximum inverse and direct magnetic entropy change values ( S M ) were −1.3 and 6.8 J/(kg K) for a melt-spun and −1.6 and 32.8 J/(kg K) for an annealed sample for a field change of 1 T. The magnetic properties and magnetocaloric effect (MCE) in GdCo 3 B 2 have been studied by Li et al [32]. The compound undergoes a magnetic Co-Co ordering at ∼160 K, and a second magnetic Gd-Gd ordering transition at 54 K. A reversible magnetocaloric effect has been observed, accompanied by a second-order phase transition at around the Gd-Gd sublattice ordering temperature.…”

a b s t r a c t Polycrystalline (PC) and single crystalline (SC) samples of La 0.7 Ca 0.3 CoO 3 (LCCO) with the perovskite structure were synthesized by conventional solid-state reaction and the floating-zone growth method. We conducted isothermal magnetization measurements of the PC and SC samples at temperatures from 2.8 K to 140 K, and evaluated the magnetic entropy change (− S M ) under zero field cooling (ZFC) and field cooling (FC) to 2.8 K. An interesting result has been obtained, where the − S M -T curves in the low temperature range show totally different features between the ZFC and FC cooling procedures. The − S M shows a large inverse irreversibility value for the ZFC process, while the − S M also shows a normal positive value, but one that is slightly larger at 2.8 K for the FC process for both samples. We also present the results of a comprehensive investigation of the magnetic properties of the LCCO system. Systematic measurements have been conducted on DC magnetization, AC susceptibility, and exchange-bias. These findings suggest that complex structural phases, including ferromagnetic and spin-glass/cluster-spinglass (SG/CSG)) states and their transitions, exist in PC samples, while there is a much simpler magnetic phase regime in SC samples. It was also of interest to discover that the CSG induced a magnetic field memory effect and an exchange-bias-like effect.

Rare‐earth‐based high‐entropy alloys (HEAs) with large magnetocaloric effect (MCE) have been recently recognized as good candidates for magnetic refrigeration. Herein, the complex magnetic transition, MCE, refrigerant capacity (RC), and magnetic‐phase diagram of single‐phase TbDyHoEr HEA are studied. It is showed in the results that due to complex magnetic transition and an ideal table‐like MCE, the RC of TbDyHoEr is significantly improved from 883.19 to 1049.22 J kg−1 by melt‐spun treatment. In terms of RC value and hysteresis performance, the melt‐spun treatment significantly improves the application potential of TbDyHoEr HEA as a high‐efficient magnetic refrigeration material, and the ideal table‐like MCE in a large temperature range enables this material to meet the requirements of both cryogenic refrigeration and mesothermal refrigeration for an Ericsson cycle.

“…Table 2 shows the maximum values of magnetic entropy change ÀDS M and adiabatic temperature change DT ad of Gd 3 -Cu 9 (OH) 19 Br 8 , compared with some other Gd-based compounds. [29][30][31][32] As shown in Table 2, the obtained values of Gd 3 Cu 9 (OH) 19 Br 8 are much larger than the values of other Gdbased compounds, indicating this compound can be considered as a potential magnetic refrigerant material at low temperature. The enhancement of magnetocaloric effect in frustrated systems with pyrochlore and Kagome lattice have been predicated in theory and further conrmed in experiment.…”
