Time Dependent Nonlinear Response of a Dipolar Glass
The competition between the development of long range order and the freezing in of disorder at low temperatures may be particularly delicate in dipolar systems. The ordering of randomly placed electric dipoles in an incipient ferroelectric host can be affected by controlling concentration, temperature, electric field, pressure or uniaxial stress. The dynamical behavior of such systems nay be experimentally probed on time scales ranging from picoseconds to hours, so they offer the prospect for detailed study of this important competition.
