Stripe order at low temperatures in with

Abstract

The stripe order in (Formula presented) with (Formula presented) was studied with neutron-scattering technique. At low temperatures, all samples exhibit hole stripe order. Incommensurability (Formula presented) of the stripe order is approximately linear in the hole concentration (Formula presented) up to (Formula presented) where (Formula presented) denotes the off stoichiometry of oxygen atoms. The charge and spin ordering temperatures exhibit maxima at (Formula presented) and both decrease beyond (Formula presented) For (Formula presented) the stripe ordering consists of the mixture of the (Formula presented) stripe order and the (Formula presented) charge/spin order. © 2000 The American Physical Society.
