我们报道了铁磁体钇铁石榴石在20 K时的5.5 K冷却伴随着磁场的增加。冷却在共线和倾斜亚晶格之间的相边界处突然停止。稀镱铁石榴石在18k和6k下分别冷却了10 K和3.7 K。
We report 5.5 K cooling at 20 K in the ferrimagnet ytterbium iron garnet accompanying an increase of magnetic field. The cooling abruptly ceases at the phase boundary between a collinear and canted sublattice configuration. A cooling of 10 K at 18 K and 3.7 K at 6 K was observed in dilute ytterbium iron garnet.
