NanoWorld Pointprobe® S-MFMR AFM probes are designed for the measurement of magnetic domains in soft magnetic samples. Due to the low coercivity of the soft magnetic AFM tip coating the magnetisation of the AFM tip will easily get reoriented by hard magnetic samples.

All SPM and AFM probes of the Pointprobe® series are made from monolithic silicon which is highly doped to dissipate static charge. The AFM tip is shaped like a polygon based pyramid.

Additionally, this sensor offers unique features:

  • soft magnetic coating on the tip side (coercivity of app. 7.5 Oe, remanence magnetization of app. 225 emu/cm3)
  • effective magnetic moment 0.75x of standard probes
  • excellent tip radius of curvature
  • magnetic resolution better than 35 nm

This AFM probe features alignment grooves on the back side of the holder chip.

Soft Magnetic Coating / Aluminum Reflex Coating

The soft magnetic coating consists of a thin soft magnetic layer deposited on the tip side of the AFM cantilever. The coercivity is app. 7.5 Oe and the remanence magnetization is app. 225 emu/cm3 (these values were determined on a flat surface). We recommend magnetizing the AFM tip by means of a strong magnet (e.g. a NdFeB magnet, a few millimeters in size) prior to the measurement.

The aluminum reflex coating deposited on the detector side of the AFM cantilever enhances the reflectance of the laser beam and prevents light from interfering within the AFM cantilever. As the coating is almost stress-free the bending of the AFM cantilever due to stress is less than 2 degrees.
