Özet
A state-of-the-art scanning Hall probe microscope (magnetic field sensitivity:spatial resolution: 30 nT/root Hz: 0.8 mu m-300 nT/root Hz : 0.25 mu m) has been used to image a range of ferromagnetic media. The technique is non-invasive and yields quantitative profiles of the stray fields near the sample surface as illustrated by images of a standard magnetic reference sample, permalloy nanostructures and colossal magnetoresistive perovskites. Rapid scanning (similar to 1 frame/12 sec) has also been used to study the domain reversal in a thin Ni him. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
