Synthesis of epitaxial Y-type magnetoplumbite thin films by quick optimization with combinatorial pulsed laser deposition

Abstract

Y-type magnetoplumbite (Ba 2Co 2Fe 12O 22:Co 2Y) epitaxial thin films with such a huge lattice parameter as 43.5 Å have been synthesized for the first time. Combinatorial thin film technology was successfully employed to eliminate an impurity phase in the film by quickly optimizing such reaction parameters as the deposition temperature and the thickness of pre-deposition of CoO layer. The coupling of combinatorial pulsed laser deposition and subsequent concurrent X-ray diffraction, both of which we have developed, is a promising way to high throughput optimization of thin film growth and properties.
