The transition temperature width also decreases for allx with theincrease of z. In order to interpret the normal state electrical properties of the samples, the quantumpercolation theory based on localized states is applied. Fitting the ... M Mazaheri,S Mofakham,M Akhavan - 《Superconductor Scie...
The effect of the external field on the weakly-discontinuous first-order phase transition is analyzed in the frame of the Landau theory. The transformation of the free energy expansion as a power series in the order parameter is suggested that maps the first-order phase transition onto the secon...

3) landau theory 朗道理论 1. On the basis of Landau theory, the free energy of boracites is regarded as the function of the three components p1, p2, p3 of the spontaneous polarization. 在朗道理论基础之上,将方硼盐的自由能始终看成自发极化矢量的3个分量p1,p2,p3的函数,利用极值条件和稳定性...
Landau theory, perovskite, phase transition, SrTiO(3)Existing experimental data for the antiferroelastic phase transition in strontium titanate are reviewed and analysed using a Landau free energy of the form G = 1/2As (coths/ Tc-colb./T)Q2 + 1/4BQ 4 + 1/6CQ 6, with A = 0·6472 ...
Landau theoryNA transitionliquid crystalsWe have developed in this study a thermodynamic model for the nematic-smectic A (NA) tricritical phase transition of a binary mixture of liquid crystals in analogy with the model for quasi fluid mixtures due to Griffiths. Using the Landau theory with a ...
