| Outline of Final Research Achievements |
Radio-frequency (RF) magnetic field over GHz plays important roles on the performances of recent advanced magnetic devices/materials such as a magnetic recording heads and magnetic nanoparticles for medical applications. This research aims at developing high-frequency magnetic force microscopy (MFM) which allows the vector detection/imaging of RF magnetic field on magnetic surfaces with nanometer spatial resolution. We have successfully developed a theory of frequency down conversion of RF filed using paramagnetic tip and built up a MFM system for RF magnetic field measurements. And also we have demonstrated the frequency down conversion detection of RF field on magnetic recording head and improved scan speed for fine magnetic domain imaging.
