研究了Er 1-xScx（）中Sc取代对铒变磁转变的影响，以寻找使用静态偏置磁场进行高效磁制冷的最佳磁热材料。我们观察到Néel温度随着温度的升高而降低。的磁热性能进行了讨论，与以前报道的相图比较。我们发现，从反铁磁类配置的铁磁类的变磁转变伴随着相对较大的磁熵变化的所有样品。所得结果将有助于进一步利用变磁相变特征研究磁制冷。
Effects of Sc substitution on metamagnetic transitions for erbium are investigated for Er1−xScx() to find optimal magnetocaloric materials for high-efficient magnetic refrigeration using static bias magnetic field. We observed that the Néel temperature decreases with increasing. The magnetocaloric properties are discussed in comparison with the previously reported phase diagram. We found that the metamagnetic transitions from the antiferromagnetic-like configurations to the ferromagnetic-like ones are accompanied with relatively large magnetic entropy changes for all the samples. The obtained knowledge would be helpful to further study on magnetic refrigeration utilizing the features of metamagnetic transitions.
