Dynamics of Spin-Charge Stripe Order in La-Based High Tc Cuprates

We have studied the striped ordered state in La-D22-x-y-D2Nd-D2y-D2Sr-D2CuO-D2be the transport and optical measurements and also by using？SR and angle-resolved photoemManagement spectroscopy （AR #）。（i）充电条纹是绝缘的还是金属的？（二）是否有证据表明沿条纹的单尺寸载波的增加？（3）超导电性是否与静态条纹顺序共存？“抵抗力和光学行为已经提供了证据，即金属电荷条纹存在于反磁性有序的旋转背景上。”这与被掺杂的镍和漫画中的绝缘条纹形成了鲜明的对比，而金属条纹是独一无二的Cuprate条纹。当前项目的亮点是，我们从霍尔效应和ARPES测量中获得了一个维度电荷动力学的明确证据。霍尔效应的演示将跨越到两个维度的地区，超过1/8。在这个制度下，超行为可能与条纹顺序共存。

We have studied the striped ordered state in LaィイD22-x-yィエD2NdィイD2yィエD2SrィイD2xィエD2CuOィイD24ィエD2 be the transport and optical measurements and also by using μ SR and angle-resolved photoemission spectroscopy (ARPES).(i) Are the charge stripes insulating or metallic?(ii) Is there evidence for one-dimensional carrier mortion along the stripes?(iii) Does superconductivity coexist with the static stripe order?The resistivity and optical conductivity have given evidence that metallic charge stripes exist on the antiferramagnetically ordered spin background. This is in contrast to the insulating striped in the doped nickelates and manganities, and the metallic stripes are unique of cuprate stripes. The highlight of the present project is that we have obtained clear evidence for one-dimensional charge dynamics from the Hall effect and ARPES measurements. The Hall effect demonstrates a crossover to the two-dimensional regime for x larger than 1/8. In this regime the superconductivity likely coexist with the stripe order.
