Temperature range of superconducting fluctuations above T c in YBa 2 Cu 3 O 7-δ single crystals
Mihael Srđan Grbić,Miroslav Požek,Dalibor Paar,Vladimir Hinkov,M. Raichle,Daniel Haug,Bernd Keimer,Neven Barišić,A. Dulčić +8 more
TL;DR: In this paper, the authors used microwave absorption measurements in magnetic fields from 0 up to 16 T to determine the temperature range of superconducting fluctuations above the critical temperature of a single crystal.

Microwave response of thin niobium films under perpendicular static magnetic fields
Dragan Janjušević,Mihael Srđan Grbić,Miroslav Požek,A. Dulčić,Dalibor Paar,Bernd Nebendahl,Thomas Wagner +6 more
TL;DR: In this paper, the microwave response of high quality niobium films in a perpendicular static magnetic field has been investigated, and the data have been analyzed by the effective conductivity model for the type-II superconductors in the mixed state.

Effects of alternating magnetic fields on the microwave absorption in ceramic high-Tc superconductors
TL;DR: In this article, the authors show that microwave absorption in high-Tc superconductors shows a complex response to applied d.c and a.c. magnetic fields, and identify a component which is due to the modulation of the magnetic flux through the sample, and components which depend on the boundary current.

An ac method for the precise measurement of Q-factor and resonance frequency of a microwave cavity
TL;DR: In this article, a new and fast method for the determination of the complex frequency shift of a microwave resonant cavity was developed based on frequency modulation of the microwave source around the cavity resonance and detection of the 2nd and 4th harmonic of the modulation frequency.

Comparison of direct and modulated microwave magnetoresistance in ceramic and single crystal YBa2Cu3O7−δ
TL;DR: A comparative study of microwave absorption in single crystals and ceramic samples of YBa 2 Cu 3 O 7−δ has made it possible to distinghuish the processes in the bulk from those in the intergranular medium as mentioned in this paper.
