Diagonal and collinear incommensurate spin structures in underdoped La2−xBaxCuO4
Abstract
We have studied incommensurate spin ordering in single-crystal underdoped La2−xBaxCuO4 with x∼0.08, 0.05, and 0.025 using neutron-scattering techniques. Static incommensurate magnetic order is observed in the La2−xBaxCuO4 (x=0.05 and 0.025) compounds with ordering wave vectors which are rotated by 45° about the commensurate (0.5,0.5,0) position, with respect to that in the superconducting x=0.08 material. These spin modulations are one …
