    摘要： Methods for spatially resolve spin resonance detection in a sample of material, with a resolution as small as 0.5 &mgr;m-1 mm. In one embodiment, a coupler having at least one pair of degenerate orthogonal modes provides an evanescent input signal along one coupler axis to the sample, to which a magnetic field is applied, and senses a spin interaction signal along another coupler axis. In another embodiment, an evanescent input signal is applied to the sample along one of two identical transmission line resonators, and a difference of the two resonator signals provides a spin interaction signal. In another embodiment, a polarized laser beam provides an evanescent input signal to the sample, and the spin interaction signal is sensed according to a second beam polarization direction. Certain ferromagnetic or ferrimagnetic molecules, such as YIG, can be used to tag selected chemical and biological molecules, using spatially resolved spin resonance detection for interrogation.

    摘要： A method for improving the magnetic resonance imaging contrast of a selected portion of a sample. A selected ferrimagnetic constituent is associated with the sample portion, by molecular or biological attachment or by some other means, so that the sample portion is distinguished from other adjacent portions of the sample that do not have the selected ferrimagnetic constituent associated therewith. Alternatively, the sample portion is suspected, but not yet confirmed, to have the selected ferrimagnetic constituent associated with it. Ferromagnetic resonance imaging is performed on the sample portion, and at least one resonance frequency ω0 of the sample portion is provided. At least one material parameter of the sample portion is measured at or near the frequency ω0, with enhanced imaging contrast relative to adjacent portions of the sample that do not have the selected ferrimagnetic constituent in association. Alternatively, the measured value is compared with a corresponding reference value for the selected ferrimagnetic constituent. If (and only if) the measured and corresponding reference values substantially agree, the selected ferrimagnetic constituent is present in association with the selected sample portion. Other parameters of the selected ferrimagnetic consituent can also be measured.
