Advanced Magnetic AFM/MFM Probes!
For measuring samples with low coercivity - Low Momеnt probes MFM_LM are the correct choice. Thanks to their own low magnetic fields low moment probes allow you to decrease the probe influence on the researched sample while scanning.
Using standart MFM tips with 40nm CoCr coating leads to perturbation of the magnetic domain pattern and tip induced local magnetization reversal of the sample (Fig. 3). Low moment MFM tips with reduced magnetic stray fields significantly reduce magnetization reversal during imaging and improve quality of the MFM results (Fig. 4).
Finally for a work in external magnetic fields, High Coercivity probes MFM_HC (500-800Oe in vertical direction and more than 2kOe in horizontal direction) is the best choice. Their coating based on Co high coercivity alloy guarantees the stable parameters of magnetic probe under the influence of the external magnetic field during measurement. |
