The NANOSENSORS™ PPP-LC-MFMR AFM probe is coated with a soft magnetic thin film enabling the measurement of magnetic domains in soft magnetic samples. Due to the low coercivity of the AFM tip coating the magnetisation of the AFM tip will easily get reoriented by hard magnetic samples.
The soft magnetic coating on the AFM tip has a coercivity of app. 7.5 Oe and a remanence magnetization of app. 225 emu/cm3 (these values were determined on a flat surface).
As both coatings are almost stress-free the bending of the AFM cantilever due to stress is less than 3.5% of the AFM cantilever length. For enhanced signal strength the magnetization of the AFM tip by means of a strong permanent magnet prior to the measurement is recommended.
This AFM probe features alignment grooves on the back side of the holder chip. These grooves fit to the NANOSENSORS Alignment Chip.
