Abstract

The out-of-equilibrium low-frequency complex susceptibility of the orientational glass methanol(73%)-β-hydroquinone-clathrate is studied using temperature-stop protocols in aging experiments. Although the material does not have a sharp glass transition aging effects including rejuvenation and memory similar to the effects in spin glasses are found at low temperatures.
