The NANOSENSORS™ PPP-LM-MFMR AFM probe is designed for magnetic force microscopy with reduced disturbance of the magnetic sample by the AFM tip and enhanced lateral resolution – compared to the standard PPP-MFMR AFM probe. The force constant of this AFM probe type is specially tailored for magnetic force microscopy yielding high force sensitivity while simultaneously enabling tapping mode and lift mode operation.
The hardmagnetic coating on the AFM tip is characterized by a coercivity of app. 250Oe and a remanence magnetization of app. 150emu/cm3 (these values were determined on a flat surface).
The SPM probe offers unique features:
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.
