论文摘要
在库酸酯超导体的开头,层间隧道(ILT)和劳伦斯·唐尼亚奇(L-D)模型,这些模型将约瑟夫森耦合连接起来的CUO平面被认为是这些材料的主要理论建议。但是,层间磁穿透深度$λ_{C} $的测量结果比ILT模型所要求的要大。在发现平面条纹和不增压的额定订单后,还可以考虑在这些介质电荷域或块之间耦合约瑟夫森。我们表明,平均内层大于层间耦合,并且与冷凝能相当,从而导致长期相位阶的超导过渡。另一个结果是,比率$ [λ_{c}/λ_{ab}]^2 $是直接比例电阻率比$ρ_C/ρ_{AB} $在超导过渡温度与多个测量的一致的超导过渡温度附近。
At the beginning of cuprate superconductors, the interlayer tunneling (ILT) and Lawrence-Doniach (L-D) models, which connect the CuO planes by Josephson coupling were considered the leading theoretical proposals for these materials. However, measurements of the interlayer magnetic penetration depth $λ_{c}$ yielded larger values than required by the ILT model. After the discovery of planar stripes and incommensurate charge ordering, it was also possible to consider Josephson coupling between these mesoscopic charge domains or blocks. We show that the average intralayer is larger than the interlayer coupling and comparable with the condensation energy, leading to a superconducting transition by long-range phase order. Another consequence is that the ratio $[λ_{c}/λ_{ab}]^2$ is directly proportional resistivity ratio $ρ_c/ ρ_{ab}$ near the superconducting transition temperature in agreement with several measurements.
