Abstract
Precise arrays of sub-100 nm diameter nanodots are fabricated from magnetic oxide perovskites with the total coverage area up to 5 mm2. Epitaxial single crystal structure of the nanodots is demonstrated by cross-sectional TEM. Low temperature MFM study confirmed the ferromagnetism of the produced particles.
