The Variable Field Module 4 (VFM4) is ideal for magnetic force microscopy and other applications where the sample has a dependence on the applied magnetic field. The VFM4 can apply adjustable in-plane magnetic fields of more than 8000 G and and out-of-plane magnetic fields of more than 1200 G. Unlike competing designs, it uses permanent magnets to avoid heating and associated drift (compatible with all MFP-3D AFMs except Origin).
Applies static in-plane magnetic fields up to ±8000 G
Applies static out-of-plane magnetic fields up to ±1200 G
High voltage option available for studies of ferroelectric and piezoelectric materials
