论文摘要
我们通过粉末中的方法（PIT）报告了ERAL2磁化线的制造，并通过磁化测量评估磁熵变化。 ERAL2坑线的磁熵变化表现出与散装对应物相似的行为，而由于周围的非磁性护套，ERAL2的体积分数的减小降低了。我们发现，另一种效果减少了ERAL2坑线围绕Curie温度的磁熵变化，并就ERAL2的磁性和鞘材料的机械性能之间的相关性讨论了其可能的起源。
We report the fabrication of ErAl2 magnetocaloric wires by a powder-in-tube method (PIT) and the evaluation of magnetic entropy change through magnetization measurements. The magnetic entropy change of ErAl2 PIT wires exhibits similar behavior to the bulk counterpart, while its magnitude is reduced by the decrease in the volume fraction of ErAl2 due to the surrounding non-magnetic sheaths. We find that another effect reduces the magnetic entropy change of the ErAl2 PIT wires around the Curie temperature, and discuss its possible origin in terms of a correlation between magnetic properties of ErAl2 and mechanical properties of sheath material.
