Spiral Spin Order and Transport Anisotropy in Underdoped Cuprates
We discuss the spiral spin density wave model and its application to explain properties of underdoped La2-xSrxCuO4. We argue that the spiral picture is theoretically well justified in the context of the extended t - J model, and then show that it can explain a number of observed features, such as th...

Summary: | We discuss the spiral spin density wave model and its application to explain properties of underdoped La2-xSrxCuO4. We argue that the spiral picture is theoretically well justified in the context of the extended t - J model, and then show that it can explain a number of observed features, such as the location and symmetry of the incommensurate peaks in the elastic neutron scattering as well as the in-plane resistivity anisotropy. A consistent description of the low doping region (below 10% or so) emerges from the spiral formulation, in which the holes show no tendency towards any type of charge order and the physics is purely spin driven. |
