制备Mn1-xCrxCoGe(x=0.01、0.015、0.02、0.03)合金带。研究了这些带材的微观结构、结构、磁性和磁热特性。 Cr替代Mn有效降低了MnCoGe合金的结构转变温度。在退火的Mn0.98Cr0.02CoGe带材中,随着温度的升高,观察到从铁磁TiNiSi型到顺磁Ni2In型状态的耦合磁结构转变。因此,这些带中呈现的接近室温的大磁热效应和同时几乎为零的磁滞损耗将有利于室温磁制冷。在测量等温磁化曲线时,采用循环法和标准法进行比较,确保结果的可靠性。
The Mn1-xCrxCoGe (x= 0.01, 0.015, 0.02, 0.03) alloy ribbons are prepared. The microstructure, structure, magnetic and magnetocaloric properties were studied in these ribbons. The substitution of Cr for Mn effectively reduces the structural transformation temperature of MnCoGe alloy. In annealed Mn0.98Cr0.02CoGe ribbons, a coupled magnetostructural transformation from the ferromagnetic TiNiSi-type to paramagnetic Ni2In-type state with the increasing temperature is observed. As a result, large magnetocaloric effect near room temperature and simultaneously almost zero magnetic hysteresis losses presented in these ribbons would be favorable to room-temperature magnetic refrigeration. In measuring the isothermal magnetization curves, both the loop and standard methods are adopted to compare and make sure the reliability of our results.
