Abstract
Purpose. This paper is devoted to investing of the effect of magnetic viscosity on the results of measurements of the main hysteresis characteristics of hard magnetic alloys in an open magnetic circuit of vibrating sample magnetometer.
Materials and methods. The studies were performed on a sample of a rapidly quenched nanocrystalline MQP-B+ brand alloy. Hysteresis properties of the alloy in an open magnetic circuit are studied: hysteresis loop, time dependences of magnetization in demagnetizing fields of different intensity, field dependences of the coefficient of magnetic viscosity and irreversible magnetic susceptibility.
Results. The dependences of the measurement results of the hysteresis properties on the measurement conditions are established. It is shown that magnetic viscosity must be taken into account when developing hard magnetic reference materials.
