Baca Física, Astronomía y Matemáticas maganites magnetoresistance Superconducting ceramics We have investigated the structural, electric transport, magnetoresitance, and magnetic properties of nominal (Bi-2223)0:95 (LSMO)0:05 thick films ground on (001)LaAlO3 (LAO) substrates. Bi-2223 is the Bi1:6Pb0:4Sr2Ca2Cu3O superconducting ceramic and La0:7Sr0:3MnO3 (LSMO) is a manganite. The X-ray diffraction patterns (XRD) of the composites exhibited most of the reflections parallel to the [00`] direction suggesting a highly oriented growth along the c-axis of LSMO, Bi-2212 and Bi-2223 layers and the preferred orientation with the crystal c-axis being perpendicular to the plane of the LAO substrate. Electric and magnetic measurements shown the presence of ferromagnetic and superconducting phases at room temperature and below to 54 K respectively. Diamagnetic and ferromagnetic hysteresis loop at 5 K and 100 K under in-plane and out-of-plane regimens and negative to positive magnetoresistance crossover into (Bi-2223)0:95(LSMO)0:05 composite at 84 K was also observed. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030392001 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
