Abstract
A device comprises a mixed sensor design with at least one superconducting loop (1) containing at least one constriction (3) and a magneto-resistive element (2) located next to the constriction (3). The device contains at least one heating element (5) that allows switching at sufficiently high frequency of at least one part of the superconducting loop (1) above its critical temperature, such that the super-current flowing through the at least one constriction (3) containing the at least one magneto-resistive element (2) is temporarily suppressed.
