Purpose: The paper presents results of the effect of structural defects on the process of magnetization in high magnetic fields in metallic glasses based on amorphous Fe60Co10W2Me2Y8B18 (where Me=Mo, Nb) Design/methodology/approach: Bulk amorphous material samples were obtained with the method of rapid radial cooling in the copper liquid-cooled mould in a protective atmosphere of inert gas. The samples in the state after solidification were then examined using a vibrating magnetometer in the magnetic fields up to 2T. Static magnetic hysteresis loops and primary magnetization curve were recorded. Findings: Changing a small amount of the element from the group of transition metals have a significant effect on the magnetic properties of the produced alloy. Depending on the substituent also the type of defects identified in the examined materials changes. Research limitations/implications: It is advisable to conduct studies on samples with compositions close to studied in this work for better prediction of magnetic properties of materials. Practical implications: Bulk amorphous metallic glass are used in the electrical industry as cores in modern high-efficiency high-power transformers. Originality/value: W Paper presents studies on the influence of structure defects on the process of primary magnetization for amorphous Fe60Co10W2Mo2Y8B18 and Fe60Co10W2Nb2Y8B18 alloys. Alloys of given composition has not yet been tested for the influence of defects on the magnetization process.
