    Abstract: A method of separating magnetic nanoparticles is described. The method comprises placing the magnetic nanoparticles in a periodic magnetic field. The periodic magnetic field varies between a first magnetic field strength and a second magnetic field strength that is higher than the first magnetic field strength. The nanoparticles may be superparamagnetic iron oxide nanoparticles.

    Abstract: An example system includes an excitation coil configured to simultaneously subject a sample volume comprising a plurality of magnetic nanoparticles to a first excitation field having a frequency ƒ H and a second excitation field having a frequency ƒ L , to generate a magnetic response including a plurality of harmonics from the sample volume. A detection coil is configured to output a response signal indicative of one or both of the plurality of harmonics or a phase lag. The example system includes a computing device configured to receive the response signal, extract one or both of the phase lag or predetermined harmonic components of the plurality of harmonics, and determine an average saturation magnetization, an average hydrodynamic volume, or a core state of the plurality of magnetic nanoparticles based on one or both of the phase lag or the predetermined harmonic components.

    Abstract: The present invention provides a method for producing a magnetic nanoparticle-coated laminate material. The method comprises coating a pair of opposed surfaces of a plurality of steel or iron/cobalt (Fe/Co) alloy film portions with a magnetic nanoparticle-containing coating. Each magnetic nanoparticle comprises a core and a shell covering at least a portion of the core. The shell and core are made of different materials selected from one or more of: iron, cobalt, nickel; and/or alloys comprising two or more of: iron, cobalt and/or nickel; and/or magnetic rare earth metals; and/or diamagnetic transition metals. The method further comprises stacking the coated film portions on top of each other such that a or each coated surface of each film portion is located adjacent a further coated surface of an adjacent film portion; and compressing the stacked coated film portions together to form a nanoparticle- coated laminate material.
