Підтримка:We are pleased to dedicate this paper about superconductivity to 70th anniversary of Academician Vadim Mikhailovich Loktev. He is always interested and prolifically works in this burning topic, without which the technologies of the future are inconceivable.
The model of hypothetical superconductivity, where the energy gap asymptotically approaches zero as temperature or magnetic field increases, has been proposed. Formally the critical temperature and the second critical field for such a superconductor is equal to infinity. Thus the material is in superconducting state always.
