Microwave fluctuational conductivity in YBa$_{2}$Cu$_{3}$O$_{7-\delta}$

Autor: SILVA, Enrico, Marcon R, Sarti S, Fastampa R, Giura M, Boffa M, Cucolo AM

We present measurements of the microwave complex conductivity at 23.9 and 48.2 GHz in YBa$_{2}$Cu$_{3}$O$_{7-\delta}$ films, in the fluctuational region above $T_{c}$. With increasing temperature, the fluctuational excess conductivity drops much fast

The interplay between superconductivity and ferromagnetism is an interesting subject of experimental and theoretical research. The observation of this effect became possible only recently due to the great progress in the preparation of high-quality h

The results of Point Contact Andreev Reflection Spectroscopy on polycrystalline RuSr$_2$GdCu$_2$O$_8$ pellets are presented. The wide variety of the measured spectra are all explained in terms of a modified BTK model considering a \emph{d-wave} symme
