Magnetically induced anisotropy of electric permittivity in the PDMS ferromagnetic gel
Abstract
<p>A polymer ferromagnetic gel is an assembly of ferromagnetic nanoparticles embedded in a gel. The finely distributed magnetic particles of iron oxide (Fe<sub>3</sub>O<sub>4</sub>) were suspended, due to adhesive forces, in the flexible matrix (poly(dimethyl siloxane) PDMS). The mean diameter of the suspended nanoparticles, equal to 8.9 nm, was determined by means of a vibrating sample magnetometer. The dispersion of the electric permittivity, studied in the frequency range of 400 Hz-5 MHz, revealed the maxima at approximately 92 kHz and 2.5 MHz. The application of the homogenous magnetic field, ranging from 0 mT to 500 mT induced the anisotropy of the electric permittivity for the mutual parallel orientation of the magnetic field, electric field and the axis of the sample. For the magnetic induction B = 500 mT the highest decrease in the electric permittivity and the shift of the maximum from 2.5 toward 2.9 MHz were found. © 2010 Elsevier B.V.All rights reserved.</p>
