Alumnus/Alumna: High-Tc-Superconductivity: Superconductivity and Correlated Electron Systems

Bernhard Muschler was member of the Gross groups as a Master and Ph.D. student between 2006 and 2012.

Master Thesis: Von einer Fermi-Flüssigkeit zu einem dotierten Antiferromagneten: Eine Raman-Studie (2007)
Ph.D. Thesis: Carrier Dynamics of Ba(Fe_1-xCo_x)₂As₂ as a Function of Doping (2012)

In his Ph.D. thesis, Berhard Muschler was studying high temperature superconductors by electronic Raman scattering. He performed a systematic light scattering study of the newly discovered iron-based superconductor Ba(Fe_1-xCo_x)₂As₂. He placed the main focus on the study of electronic properties in a doping range x in which magnetism and superconductivity are in close proximity. His experiments provided a novel view into band and momentum-dependent electronic properties. He found that the magnetic order is predominantly itinerant. Theobserved structure of the superconducting gap indicated that the coupling potential may result from magnetic fluctuations.

He left WMI in 2012 to start a career in industry. He first joined Zoller + Fröhlich GmbH and since 2018 is with Heidenhain.
