Abstract
Magnetic characterization of the magnetic field emanating from an RWH device is presented using a magnetostrictive layer as a probe between the device and the scanned SFM tip. The findings suggest a very promising technique to resolve magnetic fields laterally at least in the 100 nm realm. Other magnetosensitive properties such as the magnetoelastic and the piezomagnetic effect can be used in a similar way to infer magnetic characteristics of microstructures or of magnetic multilayers.
