Title Effect of the reversibility region on the low-temperature vortex structure imaged by Bitter magnetic decoration Type Journal Article
Year 1997 Publication PHYSICAL REVIEW B Abbreviated Journal

Abstract We have combined magnetic measurements and imaging of the vortex lattice at low fields in Tl2Ba2CuO6-delta single crystals with different oxygen content. Those with high critical temperature T-c > 80 K have a reversible region while those with low T-c < 30 K have an irreversible magnetization in the whole range of temperatures, up to T-c. The presence of the reversible region allows the formation of ordered vortex structures, while amorphous structures are obtained when no reversible region is present below T-c. The results are discussed in terms of vortex nucleation processes in the individual pinning regime.
