Research Abstract |
We studied development of the THz time domain spectroscopy system using near field effect for high sensibility and high space resolution. We used magnetic materials as a sample and/or near field scanning tips. We developed the near field imaging system using metal or magnetic material (Ba ferrite) scanning tips. We succeeded the observation of the coherent spin precession motion with the large amplitude by making metal split ring resonators on surface of magnetic material (ErFeO3). We obtained the results of the interaction between the spin system and the split ring resonators.
