Abstract

Self-assembled chains of magnetic nanoparticles embedded in a bulk polymer are prepared by thermally curing a dispersion of the nanoparticles in a liquid monomer under the application of a magnetic field. Repulsive forces between the chains cause them to assemble into an array with quasiperiodic, micrometer-scale spacing, and the chains exhibit enhanced magnetic anisotropy along the chain axis.
