Structure and Magnetic Properties of the Alloys Fe_(60)Co_(10)W_xMo_2Y_8B_(20-x) (x = 0, 1, 2)

摘要

The aim of this paper were studies of the structure and magnetic properties of the bulk Fe_(60)Co_(10)W_xMo_2Y_8B_(20-x) (x = 0, 1, 2) alloys. Ingots of the alloys were prepared by arc melting of high purity elements in an argon atmosphere. The samples in the form of plates were obtained by a rapid solidification of liquid metal in a copper mold cooled with water. Topography of produced samples were examined using a ZEISS SUPRA 35 high resolution scanning electron microscope. Furthermore, using a vibrating sample magnetometer the magnetization in high magnetic fields was studied. Moreover, from initial magnetization curves the parameters related with the Holstein-Primakoff paraprocess were determined.
