A New High-Temperature Superconductor: Bi2Sr3-x Cax Cu2O8+y.

TL;DR: A new superconductor that displays onset behavior near 120 K has been identified as Bi2Sr3-xCaxCu2O8+y, with x ranging from about 0.4 to 0.9, and electron microscopy studies show an incommensurate superstructure along the a axis that can be approximated by an increase of a factor of 5 over the subcell dimension.
