Clustering of Fe and its effect on the magnetic and the magnetocaloric properties of Co50Gd45Fe5 glassy systems
Source abstract
Abstract
Fe doped ternary alloy Co 50Gd 45Fe 5 shows an anomalous up rise in the magnetization at a temperature tP greater than the ferri − para phase transition temperature tC1 . For a magnetic field h , this abnormal nature is only observed in the sample where nanoclusters of Fe atoms are present. Study of the magneto caloric effect, micro structural analysis of magnetization and quantitative analysis of the secondary transition temperature tC2 on the Fe clustered samples confirm that the ferromagnetic interaction between Fe atoms are the only responsible factor for the abnormal increment of the magnetization. For the increment of cluster size the transition temperature tC2 increases.
