A rough estimate of the criticaltemperature was possible either with experience or on the basis of some trial runs made with larger temperature steps. This behavior of magnetic systems below a criticaltemperature is an example of collective behavior. Scaling coupling energies by the criticaltemperature gives a universal phase diagram, for systems falling into the universality class of backbone-entropy-driven unfolding as discussed previously. Convective instability analyses are useful in all three cases to predict the criticaltemperature gradient above which motion occurs. We used such a steep gradient so that the relatively large criticaltemperature difference across the slot could be measured with greater accuracy. Melting starts at nucleation sites when reaches the criticaltemperature 0 at these points, and a mush forms. It is seen that the effect of a variable v is to lower the criticaltemperature gradient and diminish the corresponding values of k2 + 12. Above a criticaltemperature gradient this conducting solution becomes linearly unstable and a convecting state is observed. We assume that the sample is cooled to a criticaltemperature with an applied field of appropriate strength. A linearized convective instability analysis predicts the criticaltemperature gradient when only the magnetic mechanism is important, as well as when both the magnetic and buoyancy mechanisms are operative. At a criticaltemperature, the latter becomes so strong that the interaction between the particles is effectively overcome, and a phase transition occurs from the ordered into the disordered phase. The improved model provides criticaltemperature of alkali metals in agreement with other experiments, but is unable to predict accurate values for the critical volume and pressure.
