| Research Abstract |
We have developed a novel scanning probe microscope (SPM) system which enables to realize magnetic resonance scanning force microscopy (MR-SFM). Up to now, we have succeeded in obtaining an atomic resolved image of Si(111)-7x7 with scanning tunneling microscopy (STM) mode and we confirmed that the developed microscope cell has an adequate rigidity. We composed a optical interferometer system and detected the signal of interferometer between the edge of optical fiber and cantilever. In addition, we confirmed that Q-factor of the cantilever is increasing with falling in temperature. However, the performance of Z-coarse approach (inertial drive) system (production of attocube) is unstable under the ultra high vacuum (10^<-8> Pa) and we have not finished the development of SPM system yet. Since the component exception for the Z-coarse approach behavior, we are sure of that SPM system perform perfectly if Z-coarse approach moves.
We developed a new method making a ferromagnetic tip which has the most suitable structure for MR-SFM measurement. This method can gives us the pillar tip which has a ferromagnet on the tip apex. The results of the elements analysis show that the pillar tip includes silicon atoms and that there is a possibility of iron silicides. However, we concluded that the pillar tip is ferromagnetic property because we can obtain the magnetic contrast with a pillar tip by magnetic force microscopy.
We performed the experiments for detecting the exchange interaction force between NiO(001) surface and tips and accumulated the experimental knowledge. Form the results of comparison of strength of exchange interaction force between the materials of tip, we concluded that the magnetic property of tip apex is the most important and we need the control of a magnetic property of tip.
