平面超导体/铁磁体混合体：磁模板诱导的电阻率各向异性
Planar superconductor/ferromagnet hybrids: Anisotropy of resistivity induced by magnetic templates
摘要：
实验研究了在铁磁BaFe_（12）O_（19）单晶上制备的超导十字形铝微桥的输运性质。结果表明，铁磁衬底中的一维畴结构可以诱导在磁畴上方形成超导沟道。这导致超导桥的电阻率的巨大各向异性，这是由沿着畴壁流动的超导电流的连续路径的出现引起的。
英文摘要：
We investigated experimentally the transport properties of a superconducting cross-shaped aluminium microbridge fabricated on top of ferromagnetic BaFe12O19 single crystal. It was demonstrated that a one-dimensional domain structure in the ferromagnetic substrate can induce the formation of superconducting channels above magnetic domains. This leads to a giant anisotropy of resistivity of the superconducting bridge, caused by the appearance of continuous paths of supercurrents flowing along domain walls.
