A 60 T non-destructive pulsed magnet is developed for use with the continuously tuneable free electron laser "FELIX". Far infrared cyclotron resonance experiments were performed using the energy range of FELIX (5-100 mu m) to study the effect of stro

Transient megagauss fields with a pulse length of few microseconds interact with sample material not only by the high field value but also by the extremely high dB/dt of ≈ 108T/s. A large number of previously unexplained hysteretic phenomena can be

In single crystals of A-site disordered perovskite manganites R1−xAExMnO3 (R = Sm, Gd, Eu, AE = Ba, Sr, x = 0.5, 0.45), we have observed the spin-glass behaviour. Applying pulsed high magnetic fields, a metamagnetic phase transition was observed in

Applying three different sophisticated growth methods using MBE we succeeded in growing unburied and buried quantum-dot structures of HgSe:Fe on a ZnSe/GaAs buffer/substrate system in (0 0 1) orientation. For the buried quantum dots the buffer/substr

Applying infrared-magneto spectroscopy in transient megagauss fields, we were able not only to observe detailed inter- and intraband resonances, but also to study the carrier dynamics due to the pronounced hysteresis effects in the magneto transmissi
