Heat capacity of high-temperature superconductors: Analysis within the framework of the impurity mechanism

  • I. A. Chaban
Article

Abstract

The impurity mechanism proposed earlier is used to interpret the heat properties of hightemperature superconductors. The expression for the heat-capacity jump describing its temperature and magnetic field dependences is obtained. An explanation of the dependence of the Sommerfeld constant on the stoichiometric composition is proposed.
