Nature of the Magnetic Order in the Charge-Ordered Cuprate La${}_{1.48}$Nd${}_{0.4}$Sr${}_{0.12}$CuO${}_4$

Abstract

Using polarized neutron scattering we establish that the magnetic order in La${}_{1.48}$Nd${}_{0.4}$Sr${}_{0.12}$CuO${}_4$ is either (i) one dimensionally modulated and collinear, consistent with the stripe model or (ii) two dimensionally modulated with a novel noncollinear structure. The measurements rule out a number of alternative models characterized by 2D electronic order or 1D helical spin order. The low-energy spin excitations are found to be primarily transversely polarized relative to the stripe ordered state, consistent with conventional spin waves.
