Abstract

Rubber composites containing Co68.15Fe4.35Si12.25B15.25 glass-covered amorphous microwires were fabricated. For samples containing 5mm long wires and randomly dispersed in the polymer matrix, our results demonstrate that the current induces resonance of circumferential permeability (magnetoimpedance resonance) resulting in a significant change of the effective permittivity of the wire-filled composites with application of a high magnetic field. For samples containing longer wires (70 mm) periodically arranged in the polymer matrix, the permittivity spectrum shows two resonance peaks due to, respectively, dipole and magnetoimpedance resonance. The induced magnetoimpedance resonance has a narrower linewidth than the dipole one as magnetic field is increased. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4712126]
