Acoustic and optical phonon dynamics from femtosecond time-resolved optical spectroscopy of superconducting iron pnictide Ca(Fe_0.944Co_0.056)_2As_2
Sunil Kumar, L. Harnagea, S. Wurmehl +2
We report temperature evolution of coherently excited acoustic and optical phonon dynamics in superconducting iron pnictide single crystal Ca(Fe_0.944Co_0.056)_2As_2 across the spi…
Ultrafast quasiparticle dynamics in superconducting iron pnictide CaFe1.89Co0.11As2
Sunil Kumar, L. Harnagea, S. Wurmehl +2
Nonequilibrium quasiparticle relaxation dynamics is reported in superconducting CaFe1.89Co0.11As2 single crystal using femtosecond time-resolved pump-probe spectroscopy. The carrie…
The electronic phase diagram of the LaO1-xFxFeAs superconductor
H. Luetkens, H. -H. Klauss, M. Kraken +16
The competition of magnetic order and superconductivity is a key element in the physics of all unconventional superconductors, e.g. in high-transition-temperature cuprates 1, heavy…
Commensurate Spin Density Wave in LaOFeAs: A Local Probe Study
H. -H. Klauss, H. Luetkens, R. Klingeler +14
We present a detailed study on the magnetic order in the undoped mother compound LaOFeAs of the recently discovered Fe-based superconductor LaOFFeAs. In particular, we…
