Beschreibung
Zusammenfassung:	A device for sensing a magnetic field, comprisinga closed superconducting loop (10) configured to collect a magnetic field to be sensed, hereinafter external magnetic field, the closed superconducting loop having a path width (wp) and being provided with a constriction (11) having a width (wc) narrower than the path width, the constriction generating a non-uniform magnetic field, hereinafter internal magnetic field, in response to the external magnetic field,a vibrating mechanical oscillator (20) coupled to, or formed by the constriction and responsive to the internal magnetic field, anda detector (60, 90, 100) configured to detect deflection or vibration of the mechanical oscillator and providing a signal indicative of the deflection or vibration.
