摘要

Nanoimprint-lithography-based molybdenum lift-off was applied to fabricate a perovskite-type La_(0.8)Ba_(0.2)MnO_3(LBMO) nanodot array on a SrTiO_3(100) substrate in combination with an in situ pulsed laser deposition (PLD) technique. We fabricated a Mo/SiO_x bilayer mask pattern to prevent the crystallization of the Mo layer even at 700 ℃ and successfully obtained a LBMO nanodot array with a dot size as small as 200 nm by removing the Mo layer using 0.1 N NaOH aqueous solution.
