Nanomagnetic Devices
In a deliberate attempt to reduce the size and resolution of nuclear magnetic resonance (NMR) spectroscopy instruments for the biochemical analysis of cells, we have written a number of papers addressing the different parts of a NMR and a magnetic resonance imaging system. One of the papers describing the use of magnetic nanoparticles to increase the sensitivity of magnetic coil detectors is described in the paper entitled “Magnetic nanostructures as amplifiers of transverse fields in magnetic resonance”. In our related previous work on magnetic nanostructures, miniaturization of single domain magnets has led to the increase in the magnetic recording density in magnetic media. To further increase this recording density, we pioneered the use of “patterned perpendicular anisotropic media” which has recently become commercially available in which single-domain nanoparticles store information on hard-disk media.
