Ultrafast Hole-Spin Dynamics in Optically Excited Bulk GaA
Michael Krauss, David J. Hilton, Hans Christian Schneider
We present experimental and theoretical results on hole-spin dynamics in bulk GaAs after ultrafast optical excitation. The experimental differential transmission are compared with…
Electronic Dynamics Due to Exchange Interaction with Holes in Bulk GaAs
Hans Christian Schneider, Michael Krauss
We present an investigation of electron-spin dynamics in p-doped bulk GaAs due to the electron-hole exchange interaction, aka the Bir-Aronov-Pikus mechanism. We discuss under which…
Ultrafast demagnetization of ferromagnetic transition metals: The role of the Coulomb interaction
Michael Krauss, Tobias Roth, Sabine Alebrand +4
The Elliott-Yafet mechanism is arguably the most promising candidate to explain the ultrafast demagnetization dynamics in ferromagnetic transition metals on timescales on the order…
Ultrafast Spin Dynamics in Optically Excited Bulk GaAs at Low Temperatures
M. Krauss, R. Bratschitsch, Z. Chen +2
This paper presents a study of electron spin dynamics in bulk GaAs at low temperatures for elevated optical excitation conditions. Our time-resolved Faraday rotation measurements y…
Spin-flip processes and ultrafast magnetization dynamics in Co - unifying the microscopic and macroscopic view of femtosecond magnetism
M. Cinchetti, M. Sánchez Albaneda, D. Hoffmann +7
The femtosecond magnetization dynamics of a thin cobalt film excited with ultrashort laser pulses has been studied using two complementary pump-probe techniques, namely spin-, ener…
