MFM Probes, 3.0N/m, 75kHz, <400Oe, ~0.3e-13EMU, 10-Pack

  • Bruker's new MESP-LM-V2 probe replaces the legacy MESP-LM probe.

    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 and aesthetics
  • 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.

  • 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.
