An approach to magnetic cooling based on the proximity effect of ferromagnets with different Curie temperatures is proposed. An analogy is drawn between the magnetotransport properties and magnetocaloric effect of an exchange nature in magnetic multilayers. It is shown theoretically that the efficiency of magnetic cooling in such heterosystems can significantly exceed the efficiency observed in homogeneous magnets. The results of experimental studies of the magnetocaloric effect in the magnetic nanostructures, as well as prospects of their use in magnetic cooling devices, are discussed.

铁磁纳米结构中磁热效应的交换增强(简述)

提出了一种基于居里温度不同的铁磁体的邻近效应进行磁冷却的方法。在磁性多层中的磁输运性质和交换性质的磁热效应之间进行类推。理论上表明,在这种异质系统中,磁冷却的效率可以大大超过在均质磁体中观察到的效率。讨论了磁纳米结构中磁热效应的实验研究结果,及其在磁冷却装置中的应用前景。
