The device includes a first body (1) of superconducting material placed in the magnetic field to be measured, an arrangement (7) suitable for successively changing the temperature of this first body above and below its transition temperature, at a first frequency, so as to generate field variations in the vicinity of the body, and an arrangement for determining the field from these variations. The arrangement includes a second body (4) of superconducting material, placed in the vicinity of the first body (1), an optical fiber (8) suitable for changing the temperature of at least one portion of this second body, above and below its transition temperature, at a second frequency greater than the first frequency, in order to generate, in this second body, current variations proportional to the field variations. These current variations are then measured and the field is determined from these variations.
