Abstract

Thin films of Y-type magnetoplumbite (Ba₂Co₂Fe₁₂O₂₂: Co₂Y) with such a huge unit cell leng as 43.5 Å has been successfully fabricated for the first time with the aid of combinatorial optimization of pulsed laser deposition process. Planning a thickness gradient CoO buffer layer on MgAl₂O₄(111) substrate was very effective for prevent the phase separation of Co deficient impurity (BaFe₂O₄) to reside in the formation of desired Co₂Y phase. From the TEM analysis, the CoO buffer layer of optimum thickness was incorporated into the Co₂Y film to make the interface with the make an atomically sharp.
