Abstract
There is disclosed a flat NMR (nuclear magnetic resonance) coil system especially adapted for evaluating thin samples of material(s), or samples in which a thin surface region of the sample is to be examined. The apparatus and method work well in a static magnetic field oriented generally perpendicular to the planes of the flat sample and coil. In one preferred mode, the coil is located approximately parallel to (and generally proximate to or in flush contact with) the surface of the subject sample, while the coil typically also is oriented so that the flux of the strong static field for performing the NMR is approximately normal to the planes of the coil and the sample surface. The coil has a wire path routed to define at least one continuous 'figure eight' double loop arrangement, to improve operational performance of the complete coil.
