Abstract
We have used a liquid-nitrogen-cooled scanning SQUID microscope to obt ain magnetic images at frequencies ranging from zero to 200 GHz, that is, from audio frequencies through the radio frequency band and into t he millimeter microwave band. We present images of thin film and bulk metallic samples, with a spatial resolution of about 30 mu m, taken us ing various readout schemes we have developed.
