DXV-8000 Vibrating Sample Magnetometry (VSM) System
Vibrating Sample Magnetometer (VSM)
High-performance VSM system designed for demanding magnetic materials R&D and production support.
Product Overview
DXV-8000 Vibrating Sample Magnetometer (VSM) is designed for high-precision magnetic measurements of advanced materials. The system supports multiple sample rod configurations allowing measurement of thin films, powders, liquids and bulk samples.
The instrument provides excellent sensitivity for materials with very low magnetic moments and is particularly suitable for multilayer films and advanced magnetic materials research.
The system can measure magnetisation curves, hysteresis loops and temperature-dependent magnetic behaviour of materials.
