An Electron Bunch Compressor Based on an FEL Interaction in the Far Infra Red
Andreas Gaupp
In this note an electron bunch compressor is proposed based on FEL type interaction of the electron bunch with far infrared (FIR) radiation. This mechanism maintains phase space de…
Mn valence instability in La2/3Ca1/3MnO3 thin films
S. Valencia, A. Gaupp, W. Gudat +5
A Mn valence instability on La2/3Ca1/3MnO3 thin films, grown on LaAlO3 (001)substrates is observed by x-ray absorption spectroscopy at the Mn L-edge and O K-edge. As-grown samples,…
Magnetic dead layers in La2/3Ca1/3MnO3 thin films probed by X-ray magnetic circular dichroism in reflection
S. Valencia, A. Gaupp, W. Gudat +3
Surface magnetic properties of perovskite manganites have been a recurrent topic during last years since they play a major role in the implementation of magnetoelectronic devices.…
Formation of Mn2+ in La2/3Ca1/3MnO3 Thin Films due to Air Exposure
S. Valencia, A. Gaupp, Ll. Abad +5
We report on the chemical stability of La2/3Ca1/3MnO3 thin films. X-ray absorption spectroscopy at the Mn L-edge and O K-edge makes evident deviations from the nominally expected (…
