Dielectric Properties of (CoFeZr)_x(PZT)100-xNanocomposites Produced with a Beam of Argon and Oxygen Ions

In this paper it was established that nanocomposite (FeCoZr)x(PZT)100-x, with x = 90.0 at.%, produced by ion sputtering with argon and oxygen beam remains under the percolation threshold. It is related to the compound structure of lms and creation of coat consisting of metallic oxides on surface of metallic phase nanogranules, which prevents electric contact between nanoparticles. Verication of the Arrhenius dependences for capacity and conductivity demonstrates that dominant part of metallic phase nanogranules has metal oxide coatings. Only a small number of nanogranules (probably around a few percent) does not have oxide coating.
