Abstract:
A study is made of the influence of a change in the topology of the Fermi surface under pressure on the superconductor-normal metal phase transition in thin films in a constant magnetic field. It is shown that in the case when a new cavity arises in the Fermi surface the region of the superconducting state in the state diagram is significantly increased with increasing pressure.
