Resumen: Since the discovery of superconductivity phenomena in mercury at 4.2¿K in 1911, great efforts have been employed to find superconducting materials that are able to operate at room temperature. Unfortunately, in spite of the discovery of different superconductors, at present, the so-called high-temperature superconductors (HTSC) maintain their superconducting behavior only a little above liquid nitrogen temperature (77¿K). Superconducting materials are characterized by their ability to transport electrical currents without losses when they are used below their critical temperature, critical current density, and critical magnetic field. Consequently, a good superconductor should have very high values of these parameters...
