Amorphous Fe 61Co10Zr4−xY2+xNb5B15(x=0, 1) samples in the form of a ribbon with a thickness of approximately 30μm and a width of about 4mm have been investigated. The ribbons were obtained by a single roller melt-spinning method with the wheel linear velocity equal to 35m/s. Microstructural studies, using X-ray spectroscopy, confirmed that samples in the as-quenched state were fully amorphous. Measurements carried out using a vibrating sample magnetometer allowed values of coercivity and saturation magnetization to be obtained. On the basis of performed measurements, it can be stated that Fe61Co8Zr4Y2Ni5Nb5B15 alloy exhibits superior soft magnetic properties compared with the Fe61Co8Zr3Y3Ni5Nb5B15alloy. The former alloy possesses: a higher value of saturation magnetization, almost double the value of magnetic permeability, approximately half the value of coercivity and substantially smaller core losses than the latter alloy.
