Dynamical Consolidation of Cobalt Nanowires for Potential Fabrication of Rare-Earth Free Permanent Magnets

Cobalt nanowires were prepared by the electroless deposition method under an applied magnetic field. Their mixtures with copper micropowders polarized under magnetic field were compacted by a hot shock-wave method for production of oriented magnetic nanocomposites for potential rare earth free magnet applications. The magnetic properties of Co nanowire/Cu micropowder composites were studied by simple RF resonant magnetometry and Nuclear Magnetic Resonance (NMR) measurements with an optical microscopy control of obtained composite one-dimensional nanotextures.
