Dynamic conductivity of semiconducting manganites approaching the metal-insulator transition

P. Lunkenheimer, F. Mayr, A. Loidl

We report the frequency-dependent conductivity of the manganite system La1-xSrxMnO3 (x <= 0.2) when approaching the metal-insulator transition from the insulating side. Results fro…

Glassy Aging Dynamics

P. Lunkenheimer, R. Wehn, U. Schneider +1

We present time-dependent dielectric loss data at different frequencies for a variety of glass formers after cooling below the glass temperature. The observed aging dynamics is des…
