Structure and Magnetic Properties of the Alloys $Fe_{60}Co_{10}W_xMo_{2}Y_{8}B_{20-x}$ (x=0, 1, 2)

The aim of this paper were studies of the structure and magnetic properties of the bulk $Fe_{60}Co_{10}W_xMo_{2}Y_{8}B_{20-x}$ (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.
