MFM - Magnetic Field Module
MFG Magnetic Field Generator – Compact, High-Performance, Integrated
The MFG is a compact magnetic field generator designed for Magnetic Force Microscopy (MFM). It provides precise in-plane (±0.6 T) and out-of-plane (±0.2 T) magnetic field control.
Compatible with Park Systems' SmartScan software, it enables fully automated sequential imaging under variable magnetic fields, without affecting AFM performance:Unchanged noise level (<50 pm)
-
No scan distortion or drift
-
No impact on AFM imaging modes
-
Available in high vacuum compatible version

(1): Mesuré et calibré à 0,3 mm de la surface, centré sur la position de l'échantillon de l'utilisateur par un capteur à effet Hall externe.
(2): Feedback Hall sensor noise: real magnetic field noise is lower than these values and only dependent of thermal noise and system vibrations. (1): Measured and calibrated at 0.3 mm from the surface, centered on the user's sample position by an external Hall sensor.
