MFM Probes, 3.0N/m, 75kHz, ~400Oe, ~1e-13EMU, 10-Pack

  • ***Note: Bruker's new MESP-V2 probe replaces the legacy MESP probe. Bruker recommends transitioning to this probe. The legacy MESP is still available for ordering while supplies last, at which point in will become obsolete.

    Bruker's MESP-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 35 nm for excellent lateral resolution for MFM, as well as other electrical and capacitance applications requiring a cantilever with conductive coating.

    The MESP-V2 has a nominal coercivity of 400 Oe (medium), and a magnetic moment of 1e-13 EMU (medium).

    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
  • This probe uses a rotated tip to provide a more symmetric representation of features over 200nm.

  • 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.
