Effect of polydispersity to specific absorption rate
Institute of Nuclear Research, P.O.Box 51, H-4001 Debrecen, HungaryThe predictions of a newly developed Bloch-Bloembergen alike analytic magnetization model are comparedto experimental results. The effect of size polydipersity on the speciﬁc absorption loss is demonstrated for themagnetic nanoparticles containing media. Speciﬁc absorpt ion rate shows resonance like behivior as a functionof particle size. The obtained results are in excellent agreement with experimental data. The dominace of theNeel relaxation over the Brownian one is demonstrated.
