Abstract

A high-Tc SQUID microscope has been constructed for imaging samples at room temperature and atmospheric pressure. The SQUID is mounted on the upper end of a sapphire rod cooled to liquid nitrogen temperature below a 3-fj. m thick silicon nitride vacuum window. This arrangement yields a SQUID-to-sample separation as low as 15 p.m. A sample can be placed on the window or scanned over the SQUID to produce magnetic images.
