论文摘要
我们研究了SB取代的CRTE_ {1-X} SB_ {X}（0 \ Leq X \ Leq 0.2）合金中的磁化效应（MCE），相对冷却能力（RCP）和结晶结构。 CRTE1-XSBX的XRD模式的rietveld细化表明，纯六边形NIAS结构与p63/MMC（194）空间组一起出现，并增加了SB替代。我们检测到基础平面A晶格参数的略有增加，C轴的降低要大得多。在50-400K的温度范围内测量磁等温线。结果表明，最大熵更改的增加| s_ {m}（t，h）|在温度范围内具有SB-subspostions（〜285-325K）。此外，RCP值在20％SB取代时增加了约33％。这些发现表明CRTE_ {1-X} SB_ {X}合金可以在纯GD元件海岸的室温磁冷却中用于磁性冷藏的Porotype磁性材料。
We investigate the magnetocaloric effect (MCE), relative cooling power (RCP) and crystalline structure in Sb substituted CrTe_{1-x}Sb_{x} (0 \leq x \leq 0.2) alloy. The Rietveld refinement of the XRD pattern of CrTe1-xSbx showed the emerging of pure hexagonal NiAs structure with P63/mmc (194) space group with increasing Sb substitution. We detect a slight increase in the basal plane a-lattice parameter, with a much larger reduction in the c-axis. Magnetic isotherms were measured in the temperature range of 50-400K. The results revealed an increase in the maximum entropy change |S_{M}(T,H)| with Sb-substitutions in the temperature range (~285-325K). Moreover, The RCP values increased by about 33% with 20% Sb substitutions. These findings suggest that CrTe_{1-x}Sb_{x} alloys can be used in room temperature magnetic cooling at fraction of the coast of pure Gd element the porotype magnetic material for magnetic refrigeration.
