Magnetic force microscopy (MFM) using an FePt high coercivity probe and Q-control in vacuum enabled an accurate magnetic domain evaluation without changing of probe magnetization in observation of Nd-Fe-B sintered magnets. The effectiveness of this technique to conventional MFM was confirmed with magnetized sample by 50 kOe pulse field and thermally demagnetized sample. And an in-situ thermal demagnetization observation of the Nd-Fe-B sintered magnets succeeded using temperature-controlled MFM.
