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…

The Excess Wing in the Dielectric Loss of Glass-Formers: A Johari-Goldstein beta-Relaxation?

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

Dielectric loss spectra of glass-forming propylene carbonate and glycerol at temperatures above and below T_g are presented. By performing aging experiments lasting up to five week…

The excess wing in the dielectric loss of glass-forming ethanol: A relaxation process

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

A detailed dielectric investigation of liquid, supercooled liquid, and glassy ethanol reveals a third relaxation process, in addition to the two processes already known. The relaxa…

Propylene Carbonate Reexamined: Mode-Coupling Scaling without Factorisation ?

J. Wuttke, M. Ohl, M. Goldammer +7

The dynamic susceptibility of propylene carbonate in the moderately viscous regime above is reinvestigated by incoherent neutron and depolarised light scattering, and c…

Wide range dielectric spectroscopy on glass-forming materials: an experimental overview

U. Schneider, P. Lunkenheimer, A. Pimenov +2

Dielectric spectroscopy is one of the most commonly used techniques for the investigation of the dynamic response of glass-forming materials. The tremendous slow-down of the partic…

Linear and non-linear dielectric spectroscopy on ammonium doped Rochelle salt

U. Schneider, P. Lunkenheimer, J. Hemberger +1

In this work we present a thorough investigation of the mixed system of Rochelle salt doped with ammonium, with 0<=x<=1 for [Na(K{1-x}(NH4)x)C4H4O6 * 4H2O]. This interesting system…
