<jats:title>Abstract</jats:title><jats:p>Thin films of Y-type magnetoplumbite (Ba<jats:sub>2</jats:sub>Co<jats:sub>2</jats:sub>Fe<jats:sub>12</jats:sub>O<jats:sub>22</jats:sub>: Co<jats:sub>2</jats:sub>Y) with such a huge unit cell length 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 MgAl<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>(111) substrate was very effective for prevent the phase separation of Co deficient impurity (BaFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>) to reside in the formation of desired Co<jats:sub>2</jats:sub>Y phase.From the TEM analysis, the CoO buffer layer of optimum thickness was incorporated into the Co<jats:sub>2</jats:sub>Y film to make theinterface with the make an atomically sharp.</jats:p>
