Relaxation dynamics and colossal magnetocapacitive effect in CdCr2S4
P. Lunkenheimer, R. Fichtl, J. Hemberger +2
A thorough investigation of the relaxational dynamics in the recently discovered multiferroic CdCr2S4 showing a colossal magnetocapacitive effect has been performed. Broadband diel…
Charge-Density-Wave like Behavior in the One-Dimensional Charge-Ordered Semiconductor (NbSe4)3I
D. Staresinic, P. Lunkenheimer, J. Hemberger +2
We report on broadband dielectric spectroscopy on the one-dimensional semiconductor (NbSe4)3I. Below the structural phase transition close to 270 K we observe colossal dielectric c…
Glassy freezing of orbital dynamics in FeCr2S4 and FeSc2S4
R. Fichtl, P. Lunkenheimer, J. Hemberger +2
We report on a thorough dielectric investigation of the glass-like freezing of the orbital reorientation-dynamics, recently found for the crystalline sulpho-spinels FeCr2S4 and FeS…
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…
