Microwave measurements of CeCoIn$_5$ using a micro-stripe line

POSTER

Abstract

We have studied microwave signal transmission through a structure consisting of a meander-type micro-strip line and a ferromagnetic or superconducting sample placed adjacent to it. The setup, which currently operates from 0 to 9 Tesla and from room temperature to 1.7 K, is suitable for studying both ferromagnetic resonance, and temperature/field dependent superconducting properties. Using this setup we have observed the superconducting transition of a single crystal of CeCoIn$_5$ in the frequency range from 5 to 19 GHz. The technique should be applicable to the study of wavelength-dependent collective modes.
