Abstract
AbstractWe have successfully fabricated LSMO grain boundary bicrystal junctions with widths down to 200 nm. The grain boundaries are symmetric with misorientation angles of 24° or 36.8°, and the microbridges are positioned across those with a precision better than ±0.5 µm. Grain boundary magnetoresistance is observed in the wider junctions but not in the most narrow junction.
