Charge Carrier Dynamics of the Heavy Fermion Metal CeCoIn Probed by THz Spectroscopy
Uwe S. Pracht, Julian Simmendinger, Martin Dressel +8
We discuss the charge carrier dynamics of the heavy-fermion compound CeCoIn in the metallic regime measured by means of quasi-optical THz spectroscopy. The transmittance of ele…
Tracing the -symmetry in iron pnictides by controlled disorder
Micha Benjamin Schilling, Andreas Baumgartner, Boris Gorshunov +8
Consecutive proton irradiation of iron pnictides reduces the superconducting transition temperature to decrease monotonically. Our systematic optical THz investigations of Ba(Fe$_{…
Shaping a superconducting dome: Enhanced Cooper-pairing versus suppressed phase coherence in coupled aluminum nanograins
Uwe S. Pracht, Nimrod Bachar, Lara Benfatto +4
Deterministic enhancement of the superconducting (SC) critical temperature is a long-standing goal in material science. One strategy is engineering a material at the nanomete…
Observing electron spin resonance between 0.1 and 67 GHz at temperatures between 50 mK and 300 K using broadband metallic coplanar waveguides
Yvonne Wiemann, Julian Simmendinger, Conrad Clauss +6
We describe a fully broadband approach for electron spin resonance (ESR) experiments where it is possible to not only tune the magnetic field but also the frequency continuously ov…
