Abstract

Single phase, c-axis oriented thin films of Y-type magnetoplumbite (Ba₂Co₂Fe₁₂O₂₂; Co₂Y) with a very large c-axis length as 43.5 Å were grown successfully by pulsed laser deposition technique. The key points were high temperature deposition and the use of CoO buffer layer inserted between the film and MgAl₂O₄(111) substrate. From the transmission electron microscope (TEM) analysis, the CoO buffer layer was consumed to make an atomically sharp interface of Co₂Y and substrate. Superconducting quantum interference device magnetometer was used to verify the high magnetic properties of the epitaxial thin films.
