Abstract
We have successfully obtained high-quality strongly underdoped Bi2Sr2CaCu2O8+x (Bi-2212) single crystals by growth in reduced oxygen partial pressure. Doping levels could subsequently be varied from underdoped through optimally doped to overdoped by a straightforward post-annealing treatment. We have characterized the obtained crystals by low-field magnetic screening experiments as well as by reversible magnetization in fields to several tesla and report the values of the penetration depth and carrier density.
