Abstract

Polymer composites containing melt-extracted (MET) ferromagnetic microwires have demonstrated excellent sensing capabilities to magnetic bias or mechanical stress.1,2 We have introduced an alternate/pulse current combined-modulation annealing (CCMA) to optimise the domain structure of MET wires and enhance their giant magnetoimpedance (GMI) response significantly as compared to conventional annealing techniques.3 Also, it has been confirmed that topological factors such as wire length play a crucial role in determining the electromagnetic (EM) properties of the wire-composites.4 Herein, we present the field/stress tunable features of microwave behaviour of epoxy-based composites containing CCMA-ed Co-based microwires of different lengths so as to look into the effects of the CCMA. A decrease-increase trend of permittivity (ε) spectra is revealed in the CCMA-ed wires composites in presence of magnetic fields. A linear positive stress-ε dependency is shown in the composite containing 25 mm CCMA-ed wires.
