Vibrating Sample Magnetometry General Platform

The CMTV-8000 Vibrating Sample Magnetometry General Platform supports multiple forms of sample rods, enabling measurements of thin films, liquids, powders, and bulk samples. It delivers excellent performance in the analysis of multilayer films and materials with very low magnetic moments.

• Measurable samples include: natural magnetic materials, particulate alloys, magnetic semiconductors, magnetic films, and thermo-magnetic effect materials.
• Measurement results include: magnetization curves, hysteresis loops, and variations of magnetization intensity over time or under different temperature/angle conditions.

• Measurement of hysteresis loops (M-H), including coercive force, residual magnetization, and saturation magnetic moment.
• Temperature-dependent magnetic moment curves (M-T), superconducting transition temperature (low-temperature option), and Curie temperature (high-temperature option).
• First-order reversal curve (FORC) measurement.
• 360° continuous electric motor-driven rotation of the sample.
• High-precision laser displacement sensor with 1 µm minimum resolution.
• Stable amplitude with high repeatability.
• Automatic sample centering with high accuracy.
• Continuous data collection at 10 ms intervals for magnetic moment, field, and temperature.
• Optional vector magnetic moment measurement.
• Expandable with various magnetic field and temperature modules.
• User-friendly operation with LabVIEW-based software.

• Thin films, powders, liquids, and bulk blocks.
• Suitable for studying magnetic semiconductors, multilayer materials, and low magnetic moment samples.
• Applications include advanced material R&D, anisotropy studies, and temperature-dependent magnetism.

The system integrates core components such as electromagnet modules, sample rod standards, and advanced vibration units.

• LabVIEW-based interface, intuitive and easy to use.
• Supports user-defined scripts and direct data export.
• Curve analysis features: zoom, translation, smoothing, and overlay.
• Compatible with Excel and Origin for post-processing.
• Automatic acquisition of magnetization, hysteresis, FORC, and temperature curves.

The dedicated CMTV-8000 electromagnet adopts a push-pull pole design with six fixed gap positions (7.5mm, 12mm, 20mm, 25mm, 28mm, and 50mm). It ensures excellent parallelism between pole surfaces, providing superior saddle areas for precise measurements.

Two magnet models are available: CMTWDS130 (2.8T) and CMTWDS225 (3.2T).

Supports simultaneous measurement of X and Y vector components of the magnetic moment. This allows detailed analysis of anisotropic materials and evaluation of vector magnetization components and susceptibility tensors. Fully compatible with both low- and high-temperature options.
