Vibrating Sample Magnetometer (VSM) Analytical Service
A Vibrating Sample Magnetometer (VSM) is a precision instrument used to measure the magnetic properties of materials. It works on the principle of electromagnetic induction: when a magnetized sample is vibrated in a uniform magnetic field, the resulting change in magnetic flux induces a voltage in a set of detection coils. This induced voltage is proportional to the magnetic moment of the sample. Magnetic characterization is critical to advancing modern technologies in materials science, electronics, biomedical engineering, and nanotechnology. Whether developing new magnetic alloys, optimizing nanocomposites, or exploring spintronic materials, precise analysis of magnetic properties provides deep insight into the structure–property relationships that govern material performance. Among available magnetic analysis techniques, the Vibrating Sample Magnetometer stands out for its sensitivity, accuracy, and wide applicability. The vibrating sample magnetometer enables the direct measurement of key magnetic parameters such as Saturation magnetization (Ms), Remanent magnetization (Mr), Coercivity (Hc), and Magnetic susceptibility (χ) under controlled temperature and field conditions. These properties are vital in understanding magnetic behavior in functional materials.

Case Study
Magnetic Characterization of Cobalt Ferrite–Lignin Hybrids
A research team develop eco-friendly magnetic nanomaterials by synthesizing cobalt ferrite–lignin hybrids via combustion of metal nitrates using two types of lignin. The hybrids were calcined at 500 °C and 900 °C, leading to significant differences in crystallinity and particle morphology. Vibrating Sample Magnetometer (VSM) analysis was employed to evaluate their magnetic properties. Measurements of M–H hysteresis loops revealed that the sample calcined at 900 °C (CF-LO900) with organic lignin exhibited enhanced magnetic performance, including higher saturation magnetization and coercivity (Hc) in the range of 1000–1500 Oe. These results were attributed to improved crystalline order and favorable cation distribution in the spinel structure. These findings demonstrate how Vibrating Sample Magnetometer (VSM) Analytical Service provides critical insights into magnetic performance related to particle structure and synthesis conditions, supporting applications in biomedical materials, drug delivery, and magnetically active composites.
