| Abstract: | The Mn-doped compounds Bi1.4La0.6Sr2CaCu2Oy were prepared by sol-gel method. The structural variation was characterized systematically by X-ray diffraction (XRD), infrared (IR) spectra and Raman scattering spectra, respectively. The electrical and magnetic properties of the compounds were investigated by the temperature dependence of resistivity (R-T) and magnetic hysteresis loop (M (H)) measurements. Results indicate that the subtle change of lattice parameters has taken place in the compounds, which is attributed to CuO2 planes canting and Mn valence alternation. In the condition of preserving Bi-2212 structure, Bi1.4La0.6Sr2CaCu2−xMnxOy compound has optimal resistivity and magnetism at x = 2%, which could provide a candidate as new barrier in Josephson junction in future. |
