摘要：

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 mum. Grain boundary magnetoresistance is observed in the wider junctions but not in the most narrow junction. (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
