Research Abstract

We have newly developed a novel two-dimensional magnetic force microscopy which enables us the simultaneous imaging of the gradients of perpendicular and in-plane magnetic field with high spatial resolution less than 10 nm. The direction of the in-plane magnetic field, which is parallel to the scanning direction, is easily selectable. We have applied this method to analyze the nano-scale magnetic domain structure and demonstrated the effectiveness of this method for various magnetic devices and materials.
