Abstract

Processes of magnetization in exchange-coupled rapidly quenched nanocrystalline alloys Nd2(Fe1-xCox)14B, where x = 0, 0.07, 0.2, 0.5, have been studied. Initial magnetization curves and interaction plots δM(H) for various demagnetized states were obtained. Based on comparison of measurement results, influence of the pinning type mechanism on magnetization process in the Nd2(Fe1-xCox)14B melt-spun ribbons is shown. Using δM(H) plots, change in intergrain exchange interaction depending on cobalt concentration in rapidly quenched Nd2(Fe1-xCox)14B nanocrystalline alloys was investigated.
