摘要
基于室温磁制冷材料应具备的条件，讨论了Ｍｎ－Ａｌ－Ｆｅ系合金Ｋ相的磁性与成分间的关系。发现合金样品在退火前磁性与Ｆｅ含量变化主线性关系，退火后呈非线性关系．还从磁性方面讨论了该系合金作为室温磁制冷材料的可行性．
The dependence of magnetism on the composition of the K phase ofMn-Al-Fe alloy system was discussed according to the critoria of selecting the magneticrefrigerant material in the room temperature range. The linear relation between magnetismand Fe concentration had been found in the non-annealed samples and the non-linear relation had been found in the annealed samples. The possibility is discussed that Mn-Al-Fe alloy acts as the magnetic refrigerant in the room temperature range in terms of the magnetism.
