Outline of Final Research Achievements |
This study reports the development of our proposed high-frequency electric field imaging measurement technique for evaluating the electric field effect of spin at the local area of a nano-magnet. Both an amplitude modulation (AM) method and a beating electric field method were suggested as a detection method of this measurement technique. For each detection method, when a Si tip approached the CPW surface, the tip oscillated with the maximum amplitude at the cantilever resonance frequency. This results means that a Si tip can detect the HF electric near-field from a CPW using each detection method. Additionally, from the HF eletric near-field distribution of the CPW, it was pointed out that the dielectric materials composing of a cantilever with the tip are improved in order to detect the HF electric field of a nano-magnet on a trasmission line in detail. Therefore, these results reveal that the high-frequency electric field imaging measurement technique can be developed newly.
