Аннотация:
On the basis of the previously proposed phenomenological material equation of a superconducting granular medium, numerical simulation of some products from granular superconductors which include, in particular, products from high-temperature superconducting ceramics (and electrodynamic processes in them) is carried out. An expression is obtained for the first critical field of the medium in question and its relation to the phenomenological parameters of the medium. A strip wire model from a granular superconducting medium is constructed, the maximum current of these wires and its dependence on the external magnetic field were obtained. An analogue of the SQUID based on the strip from a granular superconductor is proposed, it is shown that its field characteristic has similarities with the field characteristics of the classical single-contact SQUID. © 2019 Published under licence by IOP Publishing Ltd.
