Estimating the term…
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.
A device comprising a mixed sensor design with at least one superconducting loop containing at least one constriction and a magneto-resistive element located next to the constriction, characterized in that it contains at least one heating element that allows switching at sufficiently high frequency of at least one part of the said superconducting loop above its critical temperature, such that the super-current flowing through said at least one constriction containing said at least one magnetoresistive element is temporarily suppressed.
A method for suppression of low frequency noise in a magneto-resistance mixed sensor, characterized in that a local heating of parts of the mixed sensor is temporarily performed by a heating element in order to cancel the super-current sensed by at least one magneto-resistive element.
