Outline of Final Research Achievements

The purpose of this study is to develop cyclotron resonance technique of tiny samples using a microcantilever. In this method, diamagnetic components associated with cyclotron resonance is detected as a force change acting on the sample-mounted cantilever. For this purpose, we developed a solenoid magnet, a power supply, and a sample holder, and characterize their specifications. A magnetic field of 0.2 T was successfully generated with the magnet. In addition, magnetic torque signals of an organic superconductor, consistent with previous reports, were observed. Subsequently, cyclotron resonance measurements of graphite were carried out. Cyclotron resonance signal of graphite was not observed, though its diamagnetic signals were observed.
