Abstract

We report magnetic neutron-scattering measurements of incommensurate magnetic order in a superconducting single crystal of (Formula presented) We find that the incommensurate wave vectors which describe the static magnetism do not lie along high-symmetry directions of the underlying (Formula presented) lattice. The positions of the elastic magnetic peaks are consistent with those found in excess-oxygen doped (Formula presented) This behavior differs from the precise magnetic order found in the low-temperature tetragonal (Formula presented) material for which stripes of spin and charge have been observed. These observations have clear implications for any stripe model proposed to describe the static magnetism in orthorhombic (Formula presented)-based superconductors.
