Resumo
We studied magnetic interactions in promising biomedical composites based on a piezoactive PVDF matrix with a mixture of soft magnetic γ-Fe2O3 (FO) and hard magnetic CoFe2O4 (CFO) nanoparticles by conducting IRM-DCD and FORC analyses. It was determined that the addition of a mixture of soft and hard magnetic nanoparticles to the polymer base of the composite leads to an increase in the magnetic interaction fields ΔHu from ≈1300 to ≈1500 Oe and to the formation of two main magnetic phases in the composite.
