Aging and scaling laws in β-hydroquinone-clathrate

The dielectric permittivity of the orientational glass methanol(x=0.73)-β-hydroquinone-clathrate has been studied as function of temperature and waiting time using different temperature-time protocols. We study aging, rejuvenation, and memory effects in the glassy phase and discuss similarities and differences to aging in spin glasses. We argue that the diluted methanol-clathrate, although conceptually close to its magnetic pendants, takes an intermediate character between a true spin glass and a pure random-field system.
