Description
Summary:The article presents results of investigations of the structure and selected magnetic properties of a bulk amorphous alloy with the chemical composition Fe39Co33Y8B20. Alloy was produced using two methods: injection suction liquid alloy into a water-cooled copper mold. Structure of the materials was examined using X-ray diffraction. Magnetic properties were determined on the basis of measurements by the vibration magnetometer and the Faraday magnetic weight. Alloy samples produced were characterized by high Curie temperature (over 700 K) and soft magnetic properties, i.e. high saturation magnetization (1.1 T) and low coercive field value (below 200 A/m). On the basis of the primary magnetisation curves, the type of defects occurring in the samples of manufactured alloys was determined and the spin wave stiffness parameter was determined.
