Abstract
Magnetic domains of BaFe12O19 have been imagined with a scanning tunneling microscope having a flexible, magnetic tip. We have found that Co thin films evaporated on a silicon tip, integrated with a cantilever, can give high lateral resolution, below 50 nm. Therefore, we have been able to image domains and domain walls simultaneously. We have observed domains of 1.9 μm width and domain walls of 270 nm width. We explained the data using existing models.Keywords
