Fabrication and Characterization of Thin Film Copper Selenate

Cu₂OSeO₃ is a cubic chiral ferrimagnet. In addition, it is a magnetic insulator with a magnetic skyrmion lattice phase, making it a promising material for spintronics. Previous research on Cu₃OSeO₃ used only single crystal Cu₂OSeO₃ or thin layers obtained by milling down bulk single crystals. We have successfully fabricated thin film Cu₂OSeO₃ using pulsed laser deposition (PLD) and subsequent solid state reactions. Here, we present our method of thin film fabrication. We also show data characterizing the film specifically the film's crystallography, morphology, and uniformity.
