Fabrication and characterisation of La0.67Sr0.33MnO3 submicron grain boundary junctions
Paper in proceedings, 2004

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