Síntesis electroquímica de monocristales superconductores de Ba1- xKxBiO3

Abstract

A brief history of bismuth superconductivity (Bi) is given by a group of researchers from the Tata Institute of Fundamental Research in Mumbai-India, where it was found that bismuth at a temperature of 0.5 mK had a transition to a superconducting state. The explanation of this low temperature is because of its low density of carriers with one electron per hundred thousand atoms, the basic theory of superconductivity can explain this state in materials such as lead, aluminum and other metals, in terms of materials doped with Bismuth still has a large field of study. The BKBO monocrystals are of great importance, because they are oxides that with the BSC theory have critical temperatures of approximately 32 K and that does not involve transition metals.
