Anisotropy of Percolation Threshold of BaTiO3-Ni0.5Zn0.5Fe2O4 Composite Films

Abstract A systematic study on the magnetic and electrical percolation phenomena of BaTiO3 (BTO)-NiZnF2O4 (NZFO) composite films is presented in this work with the purpose of simplifying the preparation process of high-performance 1–3-type multiferroic composite films. Results show that the percolat...
