Abstract

We developed a new microfabricated cantilever with a spin-valve sensor (MR cantilever) for a scanning magnetoresistance microscope (SMRM). Since the spin-valve sensor has a self-biasing mechanism, it allows the SMRM to respond to the observed magnetic field linearly without any external bias magnetic field, hence making the SMRM more sensitive to magnetic fields. We successfully obtained SMRM images of a magnetic garnet thin film using the new MR cantilever.
