vibrating sample magnetometers (VSMs) are designed to accurately measure basic and detailed magnetic properties of a wide range of magnetic materials. These properties are obtained through major hysteresis loop, initial magnetization curve, first-order reversal curve (FORC) diagram, and ZFC/FC curve, giving rise to several magnetic parameters such as coercive field (Hc), remanence magnetization (Mr), saturation magnetization (Ms), , interaction field distribution, Curie temperature, etc. These VSMs can measure magnetic properties of bulk, thin film, powder.
