| Research Abstract |
We have newly developed a novel Near-field magnetic force microscopy (NF-MFM) which enables us to measure DC magnetic fields with field polarity near a sample surface. The sensitivity and spatial resolution of NF-MFM are drastically increased with reducing the tip-sample distance. The sensitivity is ten times larger than that of conventional MFM and 6 nm spatial resolution was obtained for high density perpendicular recording media. We have applied this method to analyze the nano-scale magnetic domain structure and demonstrated the effectiveness for various magnetic materials.
