Özet

In this study, the magnetic entropy variation in Fe74-xCrxCu1Nb3Si13B9 (x = 14 and 17) amorphous alloys was investigated. The temperature dependence of the magnetic entropy variation was calculated from the magnetization data. It was found that the Curie temperature of the sample decreases with increasing Cr content. The maximum entropy change corresponding to a magnetic field variation of 3 T is about 0.9 J/kg K for Fe60Cr14Cu1Nb3Si13B9 and 0.6 J/kg K for Fe57Cr17CU1Nb3Si13B9. (c) 2005 Elsevier B.V.
