We prepared La1.85Sr0.15CuO4/La0.7Sr0.3MnO3 nanowire network hybrid systems by means of electrospinning. From observation by scanning electron microscopy, the average diameter of the nanowires is around 220 nm and the average length can reach over 50 μm. The randomly aligned La1.85Sr0.15CuO4 and La0.7Sr0.3MnO3 nanowires exhibit numerous interconnects among each other and form a complicated, non woven hybrid network system. The nanowires are polycrystalline with a grain size at around 30 nm as confirmed by transmission electron microscopy. According to four-probe electrical transportation and magnetization measurements, superconductivity of the sample is suppressed and a positive magnetoresistance effect is observed. Measurements of M(T) and M(H) were carried out as well, revealing the soft magnetic character of the hybrid nanowire network samples.
