Abstract
A commercial atomic force microscope/magnetic force microscope (MFM) was mo dified to cool magnetic samples down to around 100 K under a high vacuum wh ile maintaining its routine imaging functionality. MFM images of a 120 nm t hick La0.7Ca0.3MnO3 film on a LaAlO3 substrate at low temperature show the paramagnetic-to-ferromagnetic phase transition. Evolution of magnetic domai ns and magnetic ripples with decreasing temperature are also observed near the edge of a 20 nm thick patterned Co film on a Si substrate.
