Bruker's MESP-LM-V2 is the established choice for Magnetic Force Microscopy.  Built on the high-performance RFESP-75 AFM probe, the hard Cobalt-Chromium coating on this tip is tailored for high-sensitivity and magnetic contrast.  This cost-effective probe has a nominal tip radius of 25 nm for excellent lateral resolution for MFM, as well as other electrical and capacitance applications requiring a cantilever with conductive coating. 

The MESP-LM-V2 has a nominal coercivity of <400 Oe (medium/low), and a magnetic moment of 0.3e-13 EMU (low). 

The reflex side of the cantilever has a Co-Cr coating for increased reflectivity up to 2.5 times that of an uncoated probe.

The new design provides:
• Tighter dimensional specifications for improved probe to probe consistency
• Tighter alignment of the tip apex to the cantilever resulting in easier laser positioning over the tip
• Improved probe quality & aesthetics
Tip Specification
MESP-LM-V2 Tip Image
Coercivity: < 400 Oe. (Medium/Low) Moment 0.3e-13 EMU (Low) The -LM product has reduced magnetic moment, sensitivity, and tip stray field, as compared to the standard MESP-V2.
Tip Height (h): 10 - 15 µm
Front Angle (FA): 17.5 ± 2.5º
Back Angle (BA): 25 ± 2.5º
Side Angle (SA): 20 ± 2.5º
Cantilever Specification
MESP-LM-V2 Cantilever Image
The Cobalt-Chromium reflective coating on the backside of the cantilever increases the laser signal (A+B) by up to 2.5 times. Although not necessary for general imaging, reflective coating is recommended for thin cantilevers (< 2.5 µm), highly reflective samples, and machine vision applications.
