Magnetic and Transport Properties of Nanoparticles Containing Ferrocolloids

  • E. Blums
Part of the NATO ASI Series book series (ASHT, volume 12)


The main concepts of magnetic properties of ferrofluids containing polydisperse particles and some new problems of nanoparticle transport properties in colloids in the presence of an external magnetic field are discussed in the paper. The following problems are considered: i) the Langevin-type magnetization of an assemble of polydisperse particles in one-particle approximation; ii) the particle magnetic interaction effects and problems of magnetogranulometry analysis; iii) the nanoparticle effective translation diffusion coefficient in the presence of uniform magnetic field; iv) thermomagnetophoretic particle transfer in nonisothermic ferrocolloids; v) nanoparticle separation in thermodiffusion column in the presence of high temperature gradients.
