Apparatus for determining magnetic properties of materials comprises a portable probe, an equipment trolley holding cryogenics and electronics and connecting cables. The probe comprises a drive coil and a correction coil, the drive coil being disposed symmetrically with respect to an inner second-order gradiometer sensor coil. Electrical connectors in the form of 2-metre long Belden (1192A) microphone cables are used to connect the apparatus on the equipment trolley to the drive coil, the correction coil and the sensor coil. The drive coil is driven so as to generate a sinusoidally varying magnetic field. The electronics comprise a flux-locked loop, a SQUID controller, a data acquisition module, which captures and processes the signals and computer. A liquid-nitrogen dewar is supported on the equipment trolley and houses a sensitive SQUID detector and a transfer coil made from copper. Possible applications of the apparatus include an intra-operative tool for sentinel lymph node detection in the treatment of breast cancer, and a non-destructive evaluation tool for detecting voids and defects in aluminum and applications in the aeronautics industry.

A well-posed magnetic imaging method is disclosed that exploits the non-linear behavior of the characteristic time scale of the Neel relaxation for obtaining accurate high-spatial resolution images of magnetic tracers. The method includes placing an object in a selection field (static field) generated by three pairs of orthogonally arranged coil (drive coils), supplying prudently choice currents to the drive coils, a zero field voxel (ZFV) is formed that can be positioned anywhere in the local region of interest (ROI), switching the magnetizing field off, and collecting an image.
