We have investigated the ferrimagnetic domain structure in a Gd{sub 0.67}Ca{sub 0.33}MnO{sub 3} thin film using magnetic force microscopy. We observe clear signs of phase separation, with magnetic islands embedded in a non-magnetic matrix. We also directly visualize the reversal of magnetization of ferrimagnetic domains as a function of temperature and attribute it to a change in the balance of magnetization of anti-aligned Mn and Gd sublattices.
