Landau Theory of the Structural Phase Transition in Antiferromagnetic CuFe0

is the nature of the structural phase transition taking place at about 260 K This transition has been detected [I] recently by differential scanning calorimetry (DSC), and

Equation (12) has all the features required to describe a second-order lamellar-to-cubic phase transition. the average principal curvatures of the bilayer. However,

We have studied the influence of these electronic interband relaxation processes, which were not taken into account in previous work [8-14], on the dynamics.. of the

In their interpretation, the tilt angle of the Sm C phase is not an order parameter, but it is defined through the wave vector of the density modulation in the

These three sets (see Table VI) fit the temperature dependence of the transverse period but they give different results for the order parameter amplitudes and

occur. we produce tilinps whick are not locally isomorphic. These packings will have as.. There is an alternative description which is often used t o describe
