Electronic excitations of potassium intercalated manganese phthalocyanine investigated by electron energy-loss spectroscopy
Benjamin Mahns, Friedrich Roth, Mandy Grobosch +2
The electronic excitations of manganese phthalocyanine (MnPc) films were studied as a function of potassium doping using electron energy-loss spectroscopy in transmission. Our data…
Electronic properties of molecular solids: the peculiar case of solid Picene
Friedrich Roth, Matteo Gatti, Pierluigi Cudazzo +5
Recently, a new organic superconductor, K-intercalated Picene with high transition temperatures (up to 18\,K) has been discovered. We have investigated the electronic propert…
New insight into the physics of iron pnictides from optical and penetration depth data
S. -L. Drechsler, H. Rosner, M. Grobosch +12
We report theoretical values for the unscreened plasma frequencies Omega_p of several Fe pnictides obtained from DFT based calculations within the LDA and compare them with experim…
High-Field Pauli-Limiting Behavior and Strongly Enhanced Upper Critical Magnetic Fields near the Transition Temperature of an Arsenic-Deficient LaO_0.9F_0.1FeAs_(1-δ) Superconductor
G. Fuchs, S. -L. Drechsler, N. Kozlova +14
We report upper critical field B_c2(T) data for disordered (arsenic-deficient) LaO_0.9F_0.1FeAs_(1-delta) in a wide temperature and magnetic field range up to 47 T. Because of the…
Optical Study of LaO_0.9F_0.1FeAs: Evidence for a Weakly Coupled Superconducting State
S. -L. Drechsler, M. Grobosch, K. Koepernik +10
We have studied the reflectance of the recently discovered superconductor LaO_0.9F0.FeAs in a wide energy range from the far infrared to the visible regime. We report on the observ…
