Keywords:ordered alloy, topotactic, superlattice

Since it is difficult to create ordered structures on the atomic scale, effective crystal growth method has not been established for ordered alloys with alternating layers of Co and Ni, which are expected as high-performance rare earth-free magnet.
We have suggested a synthetic strategy to convert metal oxides into metals as precursors, and applied the method of topotactic reduction with hydrides to this.
In this study, we fabricated metal oxide artificial superlattice thin films, and investigated the structure and magnetism of the transformed crystalline phase.
