Room-temperature-ferroelectric ferromagnetic Co-substituted BiFeO3 is a promising candidate for low consuming non-volatile memory devices. We fabricated BFCO nanodots using HSQ hole-array-mask fabricated by electron beam lithography. In this presentation, we will report on the ferroelectric and magnetic domain changes in BFCO nanodots via poling, which are characterized in detail by PFM and MFM. In addition, we will discuss the achievement of high-quality nanodots by improving the process.
