The vortex depinning transition in untwinned YBaCuO using complex impedance measurements
Alain Pautrat, Christophe Goupil, Charles Simon +3
We present surface impedance measurement of the vortex linear response in a large untwinned YBCO crystal. The depinning spectra obtained over a broad frequency range (100 Hz- 30 MH…
Non-linear electrical response in a charge/orbital ordered CaMnO crystal : the charge density wave analogy
A. Wahl, S. Mercone, A. Pautrat +2
Non-linear conduction in a charge-ordered manganese oxide PrCaMnO is reported. To interpret such a feature, it is usually proposed that a breakdown of the cha…
Electrodynamics of the vortex lattice in untwinned YBaCuO by complex impedance measurements
A. Pautrat, A. Daignere, C. Goupil +4
We report complex impedance measurements in an untwinned YBaCuO crystal. Our broad frequency range covers both the quasi static response and the resistive response of the vortex la…
Anomaly in the dielectric response at the charge orbital ordering transition of crystalline Pr0.67Ca0.33MnO3
Silvana Mercone, Alexandre Wahl, Alain Pautrat +2
The complex impedance of a Pr0.67Ca0.33MnO3 crystal has been measured. The frequency dependence is studied for a wide range of temperatures (50K-403K) and is found to be characteri…
