摘要
为了选择合适的磁致冷材料 ,确立更准确的测量方法 ,利用永磁体作磁场 ,采用高灵敏温度传感器 ,直接测量了Gd5(SixGe1-x) 4合金样品的ΔTad-T曲线 ,并与文献中相同成分的样品间接测量的结果进行了比较 .
For the purpose of selecting proper megnetic refrigeration materials and establishing more accurate measurement method, ΔT ad T curves of Gd 5(Si x Ge 1-x ) 4 alloy samples were determined directly by using a high sensitive thermosensor in the magnetic field produced by permanent magnet in the temperature adjusted chamber.The measured results were analyzed and compared with that of the samples with the same composition as given in the literatures,and the measurement errors were discussed.
