| Research Abstract |
We investigated the origin of the high resolution and low magnetic disturbance of CNT-MFM probes. Experiment shows that the coat materials with saturation magnetization are better, and the thickness of 6-10 nm is appropriate. The micromagnetic simulations show that the total diameter of the probe should be less than 50 nm. The stray field of the CNT-MFM probes is smaller than the conventional pyramidal probes, which contributes to the low magnetic disturbance.
