Abstract

The field-induced phase transition driven by electric field was observed in poly(vinylidene fluoride - hexafluoropropylene) (P(VDF-HFP)) 90/10 wt% copolymers. Experimental results indicated that the electric field may remarkably affect the remanent polarization in terms of changing the D-E loop forms from double loops to single loop, starting from 68 MV/m, and completing at 216 MV/m. It was found that the remanent polarization as well as the piezoelectric constant d₃₁ had a linear relationship with the poling electric field in above electric field range. Thus the magnetoelectric (ME) coupling coefficient α_ME in P(VDF-HFP)/Metglas laminates increased with the poling electric field. Moreover, the cyclic poled ME device demonstrated different peak d.c. magnetic bias field H_DC on the α_ME - H_DC curves from conventional room temperature poled ones. The peak ME coefficient obtained was ∼4 V/cm·Oe.
