对磁铅石型铁氧体,尖晶石型铁氧体,石榴石型铁氧体以及正铁氧体部分样品的磁卡效应进行了实验研究,研究了非磁性离子的代换对居里温度以及磁熵变的影响。The magnetocaloric effect of several ferrite specimens, with magnetoplumbite structure, spinel structure, garnet structure and perovskite structure respectirely, have been studied experimentally. The effect of substitution of non-magnetic ions on Cu-rie temperature and magnetic entropy are also reported.
