Memory effects and KWW relaxation of the interacting magnetic nano particles

Abstract

Carry out of the mechanism of the slow relaxation in the interacting magnetic nano particles which are used technology and biomedicine applications such as drug delivery, ferrofluids mechanics, magnetic data storage, sensors, magnetic resonance imaging and cancer therapy is very important. Therefore in this study, to model of the relaxation and investigate frequency and temperature behavior depends on slow relaxation, we used a simple operator formalism. We show that relaxation deviates from Debye and obeys to KWW and frequency and temperature behavior depends on KWW relaxation. We conclude that obtained results are consistent with experimental results and the simple model, presented here, is very useful to model the slow relaxation of the interacting nano particles.http://arxiv.org/abs/2103.00850
