Transport properties of bicrystal Josephson junctions in Y-Ba-Cu-O films grown by liquid phase epitaxy
We studied charge transport across 24/spl deg/, 36/spl deg/, 45/spl deg/ symmetrical and 45/spl deg/ asymmetrical grain boundaries (GB's) in YBCO bicrystals grown by liquid phase epitaxy (LPE). We show that transport properties of symmetrical GB's are similar to those in bicrystals formed...

Summary: | We studied charge transport across 24/spl deg/, 36/spl deg/, 45/spl deg/ symmetrical and 45/spl deg/ asymmetrical grain boundaries (GB's) in YBCO bicrystals grown by liquid phase epitaxy (LPE). We show that transport properties of symmetrical GB's are similar to those in bicrystals formed by various physical vapour deposition (PVD) methods while for 45/spl deg/ asymmetrical GB's, a difference between transport properties of LPE and PVD bicrystals has been found. In particular, in contrast to PVD bicrystals, selected LPE samples demonstrate regular magnetic interference patterns. In an agreement with transmission electron microscopy data, this result suggests better quality of 45/spl deg/ asymmetrical GB's in LPE films. |
