Research Abstract |
We studied low energy electronic properties of strongly correlated electron systems by using microwave. In uranium heavy-fermion compound, we observed cyclotron resonance for the first time, from which we determined the electronic mass structure of the main Fermi surface sheets in the so-called hidden-order phase. We also measured the magnetic penetration depth in iron-based superconductors and determined the superconducting gap structure. We also found the quantum critical point inside the superconducting phase.
