Abstract

This paper uses complex magnetic susceptibility measurements to investigate the effects of different coatings on the susceptibility of iron oxide nanoparticles. The two coatings used in these measurements are aminosilane and carboxymethyl-dextran. Susceptibility measurements are carried out over a range of frequencies from 10 KHz to 1 MHz using a differential impedance method. The differential impedance measurement setup is validated by measuring the susceptibility of ferrofluids and comparing the results to values previously published in literature. The theoretical relaxation times based on Brownian and Neel mechanisms are used to predict the resonance frequency of imaginary part of complex susceptibility for iron oxide nanoparticles.
