Complex microwave conductivity of Na-DNA powders

H. Kitano, K. Ota, A. Maeda

We report the complex microwave conductivity, $σ = σ_{1} - i σ_{2}$ , of Na-DNA powders, which was measured from 80 K to 300 K by using a microwave cavity perturbation technique. We found th…

Dynamic fluctuations in the superconductivity of NbN films from microwave conductivity measurements

Takeyoshi Ohashi, Haruhisa Kitano, Astutaka Maeda +2

We have measured the frequency and temperature dependences of complex ac conductivity, σ(ω)=σ_1(ω)-iσ_2(ω), of NbN films in zero magnetic field between 0.1 to 10 GHz using a microw…

Critical microwave-conductivity fluctuations across the phase diagram of superconducting La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$ thin films

Haruhisa Kitano, Takeyoshi Ohashi, Atsutaka Maeda +1

We report a systematic study of the dynamic microwave conductivity near $T_{c}$ for La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$ (LSCO) thin films with $x$ =0.07 to 0.16. The strong frequency dependence o…
