Description
The NANOSENSORS™ PPP-MFMR AFM probe is our standard probe for magnetic force microscopy providing a reasonable sensitivity, resolution and coercitivity. It has proven stable imaging of a variety of recording media and other samples. The force constant of this 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 tip is optimized for high magnetic contrast and high lateral resolution of considerably better than 50 nm. The coating is characterized by a coercivity of app. 300 Oe and a remanence magnetization of app. 300 emu/cm3 (these values were determined on a flat surface).
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 tip coating the magnetisation of the tip will easily get reoriented by hard magnetic samples. The soft magnetic coating on the tip has a coercivity of app. 0.75 Oe and a remanence magnetization of app. 225 emu/cm3 (these values were determined on a flat surface).
The NANOSENSORS™ PPP-LM-MFMR AFM probe is designed for magnetic force microscopy with reduced disturbance of the magnetic sample by the tip and enhanced lateral resolution – compared to the standard PPP-MFMR probe. The force constant of this 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 tip is characterized by a coercivity of app. 250 Oe and a remanence magnetization of app. 150 emu/cm3 (these values were determined on a flat surface).
