Flux pinning effect of embedded carbon nanotubes in Bi2Sr2CaCu2O8

The enhancement in the critical current density J(c) is one of tile most im portant challenges in superconductivity. Since the discovery of high temper ature superconductors like YBa2Cu3O7-x, ((1)) and subsequently with the adv ent of BiSrCaCuO, ((2)) TlBaCuO, ((3)) and HgBaCuO ((4)) families, a great deal of research has been devoted to improve their transport properties and specially to enhance J(c). In this work, we address a new technique develo ped in order to increase J(c) in a sample of BSCCO (2212) embedded in carbo n nanotubes.
