铜氧化物中的条纹与超导电性

Stripes and Superconductivity in Cuprates

John M. Tranquada

摘要:

掺杂到铜酸盐母体化合物的CuO 2平面中的空穴挫败反铁磁有序。自旋和电荷条纹的发展在相互竞争的磁能和动能之间提供了一种折衷。静态条纹秩序已被观察到,只有在某些特定的化合物,但也有迹象表明,动态条纹的相关性是常见的铜酸盐。虽然条纹序不利于超导相位相干,但条纹与强配对是相容的。具有讽刺意味的是,磁场诱导的条纹秩序似乎增强了平面内超导秩序的稳定性。

英文摘要:

Holes doped into the CuO2 planes of cuprate parent compounds frustrate the antiferromagnetic order. The development of spin and charge stripes provides a compromise between the competing magnetic and kinetic energies. Static stripe order has been observed only in certain particular compounds, but there are signatures which suggest that dynamic stripe correlations are common in the cuprates. Though stripe order is bad for superconducting phase coherence, stripes are compatible with strong pairing. Ironically, magnetic-field-induced stripe order appears to enhance the stability of superconducting order within the planes.
