摘要：
NiFe thin films of 20 nm thickness were selectively oxidized using an atomic force microscope (AFM). The dot structures of NiFe -oxide were fabricated by applying a pulse voltage to the AFM cantilever. The height and diameter of the dots were controlled by changing the pulse voltage. The diameter of the dots did not strongly depended on the duration of the pulse. These experimental results are supported by the theoretical model assuming the threshold electric field strength for the oxidation.
