CMT-130 High - Sensitivity Vibrating Sample Magnetometer

CMT-130 VSM System in Memphis University

The CMT-130 High-Sensitivity Vibrating Sample Magnetometer is designed to measure the fundamental magnetic properties of a wide range of materials. It enables precise analysis of magnetization curves, hysteresis loops, demagnetization curves, and related parameters such as saturation magnetization, residual magnetization, coercive force, maximum magnetic energy product, and magnetic permeability.

The system supports diverse sample types, including powders, granules, flakes, and bulk materials, making it ideal for both research laboratories and industrial applications.

• High sensitivity measurement down to 5×10⁻⁵ emu
• Wide measurement range: 10⁻³ emu – 300 emu
• Capable of analyzing multiple sample types (powder, film, liquid, bulk)
• Provides full suite of magnetic parameters including Curie temperature and susceptibility
• Reliable repeatability and stability during long-term operation
• User-friendly operation with integrated software for automated measurements and data processing

• Powders and fine particles
• Granules and flakes
• Thin films and coatings
• Bulk magnetic materials
• Research applications in magnetic materials characterization

• Model: VSM-130C&D
• Direct system parameter setup and data visualization
• Raw data files saved in *.13D format, compatible with Excel and Origin for further processing
• Display of multiple measurement curves, including: Magnetization curve Hysteresis loop Demagnetization curve Fast MH loop Background curve
• Curve operations: zoom, smoothing, translation, partial selection, and print/export functions
• Automatic conversion of open-circuit VSM measurements to intrinsic (closed-circuit) magnetic curves (when demagnetization factor and density are known)
• Real-time calculation of parameters under both SI and Gaussian units: Saturation magnetic moment/magnetization Residual magnetic moment/magnetization Coercive force and intrinsic coercive force Rectangular coefficient Maximum magnetic energy product Loop area
