Abstract: The present invention discloses a sensor device comprising a probe carrying a three-dimensional magnetic field sensor. The probe has a conical tip portion with an edge being configured as the three-dimensional magnetic field sensor. The sensor at the edge of the tip comprises at least three Josephson junctions, each junction being formed of a superconducting layer interrupted by a barrier. The barrier comprises a non-superconducting layer or a geometrical constriction. The conical tip portion of the probe forms a tapered three-dimensional structure having at least one arc-like part crossing the opening of the tip portion such that the apex has a closed-loop basis and a plurality of complimentary spaced-apart facets defined by the at least one arc, thereby enabling measurement of both in-plane and out-of-plane magnetic fields separately.
