Structural, Electrical and Magnetic Study of BiNixFe1-xO3 (x=0-1) Spin-coated Ferrite Films

Aims: To fabricate BiNixFe1-xO3 (x=0-1) ferrite films on a Si substrate with a thin Pt buffer using the spin coating method.

Study Design: The focus of the study was two-fold: to examine the properties of the BiNixFe1-xO3 (x=0-1) family of materials and to determine whether Pt is a suitable element for preventing diffusion between the film and the substrate.

Place and Duration of Study: Dept. of Physics and Dept. of Electrical & Computer Engineering, Aristotle University of Thessaloniki and Dept. of Materials Science and Engineering, University of Ioannina, between November 2019 and November 2021.

Methodology: The films were manufactured with the spin-coating method, and characterization was performed with various methods, including XRD, SEM/EDAX and VSM measurements

Results: Pt can prevent diffusion effects. The target material was not formed, probably due to the low annealing temperature. No magnetoelectric properties were detected.

Conclusion: The spin-coating method is not recommended for the fabrication of these materials.
