Abstract

A technique for the fabrication of sub-100nm diameter magnetic perovskite nanodots that maintain their crystallinity, epitaxial structure, and ferromagnetic properties after the fabrication process, was investigated. The materials that are patterned into nanodots are La2/3Sr 1/3MnO3 (LSMO) and SrRuO3. To investigate the magnetic properties of the nanodots, magnetic force microscopy (MFM) measurements on the SRO nanodot arrays were performed. The results show that since magnetic perovskites can be combined epitaxially into multilayer heterostructures with perovskite ferroelectrics and high-temperature superconductor, this technique opens up the possibility of fabricating heterostructures with unexplored functionalities.
