From: Magnetoelectricity in CoFe2O4 nanocrystal-P(VDF-HFP) thin films
Effective permittivity and loss tangent of the ferrites / polymer thin films. Effective permittivity (a) and loss tangent (b) of CFO/P (VDF-HFP) nanocomposite thin films with CFO fractions from 0 to 30 wt.%. (c) Effective permittivity of the CFO/P(VDF-HFP) as a function of composition at 100 to 1 MHz. (d) Effective permittivity of CFO/PVP films.
