Description

f = 75 kHz   |   k = 2.8 N/m   |   tip coating: soft magnetic

Soft Magnetic Coating - Magnetic force microscopy - Reflex coating NanoWorld Pointprobe®
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 tip coating the magnetisation of the tip will easily get reoriented by hard magnetic samples.

All probes of the Pointprobe® series are made from monolithic silicon which is highly doped to dissipate static charge. The tip is shaped like a polygon based pyramid with a typical height of 10-15 µm.

Additionally this probe offers unique features:
soft magnetic coating on the tip side (coercivity of app. 0.75 Oe, remanence magnetization of app. 225 emu/cm3)
effective magnetic moment 0.75x of standard probes
tip radius of curvature of the coated tip < 30 nm
magnetic resolution better than 35 nm

Soft Magnetic Coating / Aluminum Reflex Coating
The soft magnetic coating consists of a thin soft magnetic layer deposited on the tip side of the cantilever. The coercivity is app. 0.75 Oe and the remanence magnetization is app. 225 emu/cm3 (these values were determined on a flat surface). We recommend magnetizing the 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 cantilever enhances the reflectance of the laser beam and prevents light from interfering within the cantilever. As the coating is almost stress-free the bending of the cantilever due to stress is less than 2 degrees."
