Abstract
A superconducting magnetometer, using a superconducting compound at the temperature of liquid nitrogen, is disclosed. It consists in the use, as a sensitive element, of a piece of superconducting material with a central constriction enabling the demarcation of a channel in which the number of useful, intrinsic loops is sufficiently limited for the sensitive element to behave like a DC SQUID with a single loop.
