    Abstract: A system and method for locating magnetic material. In one embodiment the system includes a magnetic probe; a power module in electrical communication with the magnetic probe to supply current to the magnetic probe; a sense module in electrical communication with the magnetic probe to receive signals from the magnetic probe; and a computer in electrical communication with the power module and the sense module. The computer generates a waveform that controls the supply of current from the power module and receives a signal from the sense module that indicates the presence of magnetic material. The magnetic probe is constructed from a material having a coefficient of thermal expansion of substantially 10−6/° C. or less and a Young's modulus of substantially 50 GPa or greater. In one embodiment magnetic nanoparticles are injected into a breast and the lymph nodes collecting the particles are detected with the probe and deemed sentinel nodes.

    Abstract: A multicore magnetic particle. In one embodiment, the magnetic particle includes a plurality of superparmagnetic cores embedded in a non-magnetic matrix. In another embodiment, the effective anisotropy energy barrier of the particle is larger than the sum of the anisotropy energy barriers of the individual superparamagnetic cores. In yet another embodiment, the superparamagnetic cores are close enough to interact magnetically by exchange coupling and dipole interaction. In still yet another embodiment, the specific loss power of the magnetic particle is greater than the specific loss power of an equivalent mass of individual superparamagnetic cores.
