Abstract
We have designed and constructed a high-T-c superconducting quantum interfe rence device (SQUID) microscope with a sample chamber isolated by a shutter . It can image magnetic distributions of samples at both room temperature a nd 77 K. According to our scheme, the separation of the sample from the SQU ID can be less than a few micrometres, in principle. We have successfully i maged a trapped flux in a YBa2Cu3O7-y thin-film ring at 77 K and a printout of a laser printer at room temperature.
