摘要：

In this work, it is used a phenomenological model to predict the thermomagnetic properties for Cu-1.5[Fe(CN)(6)].zH(2)O and Mn-1.5[Fe(CN)(6)].zH(2)O through making modeling of experimental isofield thermo-magnetization curves. Consequently, the magnetocaloric effect (MCE) of Cu-1.5[Fe(CN)(6)].zH(2)O and Mn-1.5[Fe(CN)(6)].zH(2)O, in the vicinity of ferromagnetic phase transition, is simulated, calculating MCE parameters. The comparison between MCE of Cu-1.5[Fe(CN)(6)].zH(2)O and Mn-1.5[Fe(CN)(6)].zH(2)O samples, and other some reported magnetic materials has been done, showing that MCE parameters of Cu-1.5[Fe(CN)(6)].zH(2)O and Mn-1.5[Fe(CN)(6)].zH(2)O samples are larger than some MCE parameters of these reported magnetic materials. The behavior of MCE in Cu-1.5[Fe(CN)(6)].zH(2)O and Mn-1.5[Fe(CN)(6)].zH(2)O recommends that they can fruitfully be utilized as cryogenic magnetic refrigerants between 5 and 25 K especially in radiation detectors for outer space research.
