Abstract
High resolution Bitter patterns have been analyzed to reveal the static structure of the flux lattice in the low field mixed state of BSCCO (2212). For field cooled experiments with Bllĉ, the in-plane effective mass anisotropy distorts the lattice. Measured distortions in the range of 5-10% are well below that expected from resistance anisotropy and observed in YBCO (123) decorations. At low fields, the pattern is otherwise amorphous. Increasing the field above -20G results in a sudden transition into an hexatic phase. The signature of the hexatic is long range orientational order, with the positional order remaining short ranged. The crossover field, lowered to -8G upon annealing the sample for 24 hours in 1 atm O2, is, by inference, strongly correlated with pinning strength. Rotating the applied field away from the ĉ axis results in a dramatic new structure-a periodic array of vortex chains with an intervening hexagonal lattice. In extremely anisotropic systems an attractive vortex-vortex interaction perpendicular to the rotation axis stabilizes a chain structure.
