To the microscopic theory of the superconductive phase in antiferromagnetic metal compounds

Abstract

The theory of the conductivity in antiferromagnetic metal compounds is constructed on the basic of the fluctuational theory of the magnetic superconductors. The superconductor in which there exist localized magnetic moments was considered. It is supposed that magnetic moments are orientated antiferromagnetically in basis plane of the crystal. An estimation for the critical temperature was obtained and necessary and enough conditions of the appearance of high-temperature superconductive phase in rare earth metal compounds were got. The criterion of an appearance of the high-temperature superconductive phase in antiferromagnetic compounds is found.
