Magnetodielectric effects in hybrid magnetorheological suspensions
E-mail:
The magnetodielectric material obtained is a hybrid magnetorheological suspension (MRS-hybrid) which contains polyurethane sponge foam, magnetorheological suspensions (MRS) and polymerized silicone rubber. We create a plane capacitor based on MRS-hybrid. Using a programmable bridge we measure the capacitance C and the dissipation factor D of the capacitor as a function of intensity H of a constant magnetic field, and as a function of frequency f of an electric field. We determine the components e0 (relative dielectric permittivity) and e00 (dielectric loss factor) of the complex dielectric permittivity e* of MRS-hybrid. We present and discuss the obtained results.
