Abstract

Self-assembly and flux closure studies of magnetic nanoparticle rings - DTU Orbit (17/04/14) Self-assembly and flux closure studies of magnetic nanoparticle rings - DTU Orbit (17/04/14) Self-assembly and flux closure studies of magnetic nanoparticle rings Thermoremanent magnetic nanoparticles (MNPs) can self-assemble into rings through dipolar interactions, when dispersed under appropriate conditions. Analysis of individual MNP rings and clusters by off-axis electron holography reveals bistable flux closure (FC) states at ambient temperatures, and their reversible switching by magnetic field gradients. We introduce a line-bond formalism to describe the coupling between MNPs.
