(2002)</i><br /><br />Dielectric relaxation spectroscopy (1 Hz – 20 GHz) has been performed on supercooled glass-formers from the temperature of glass transition (Tg) up to that of melting. Precise measurements particularly in the frequencies of MHz order have revealed that the temperature dependences of secondary relaxation times in well above Tg deviate from the Arrhenius relation below Tg: the process does not merge with the process around the dynamical crossover temperature in contradiction to previously speculated extrapolations.
