METHOD FOR DETERMINING THE CHANGES OF THE COMPONENTS OF THE ENERGY OF A SOLID CRYSTAL BODY AT THE SECOND-ORDER PHASE TRANSITION THAT ARE CAUSED BY STRUCTURAL AND TEMPERATURE DISORDERING EFFECT

摘要

The proposed method for determining the changes of the components of the energy of a solid crystal body at the second-order phase transition that are caused by structural and temperature disordering effect implies the analysis of the absorption edge of optical radiation by the solid body under varying temperature. The method is distinctive by determining the parameters that characterize the change of the aforesaid components of the energy of the solid crystal body using the property of integrity of energy in the transition from a low-energy phase to the high-energy phase under the temperature that corresponds to the second-order phase transition.
