Magnetization Processes of Exchange Coupled Nd2(Fe,Co)14B Alloys in Various Demagnetized States
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, a change in intergrain exchange interaction depending on cobalt concentration in rapidly quenched Nd2(Fe1 – xCox)14B nanocrystalline alloys was investigated.
期刊介绍:
The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
