Charge stripes and spin correlations in copper-oxide superconductors

TL;DR

This paper demonstrates that stripe charge order and spin correlations in cuprate superconductors can be quantitatively explained by neutron scattering data, supporting the stripe model of high-temperature superconductivity.

Contribution

It provides a quantitative interpretation of spin fluctuations in cuprates based on stripe charge segregation, linking neutron diffraction and scattering results.

Findings

Charge stripes segregate holes in cuprates.

Spin fluctuations are consistent with stripe order.

Neutron scattering data supports stripe-based models.

Abstract

Recent neutron diffraction studies have yielded evidence that, in a particular cuprate family, holes doped into the CuO(2) planes segregate into stripes that separate antiferromagnetic domains. Here it is shown that such a picture provides a quantitatively consistent interpretation of the spin fluctuations measured by neutron scattering in La(1.85)Sr(0.15)CuO(4) and YBa(2)Cu(3)O(6+x).
