Magnetic multiparticle systems and symbolic dynamics
NATO ADV SCI I E-APP 349 (1998) 317-342
Abstract:
The aim of this review is to describe some aspects of the dynamic properties of magnetic multiparticle systems in the micrometer range. These particles include monodisperse magnetic microspheres, and magnetic holes, i.e. nonmagnetic particles dispersed in ferrofluids.The complementary use of analogue simulations and computer simulations to explore the dynamic properties is demonstrated.The ability to describe the complex dynamics of magnetic holes in quantitative symbolic dynamic terms using the notion of knot- and braid theory will be discussed. In particular, statistical analysis of braid words, diffusion, memory effects and correlations for the complex dynamics is illustrated.Metallization of fluid hydrogen

Nucleation theory of magnetization switching in nanoscale ferromagnets
NATO ADV SCI I E-APP 349 (1998) 307-316
Abstract:
A nucleation picture of magnetization switching in single-domain ferromagnetic nanoparticles with high local anisotropy is discussed. Relevant aspects of nucleation theory are presented, stressing the effects of the particle size on the switching dynamics. The theory is illustrated by Monte Carlo simulations and compared with experiments on single particles.Phase diagram and storage capacity of sequence processing neural networks
