First Order Transition of the Vortex Lattice in Disordered Bi-2212 Crystals

C. J. van der Beek, I. Abalosheva, M. Konczykowski +3

Using differential magneto-optical imaging, we address the question of mesoscopic inhomogeneity in underdoped Bi-2212 single crystals. Among other features, it is shown that an ano…
