Abstract

We have carried out elastic neutron scattering measurements on La $_{1.875}$ Ba $_{0.075}$ Sr $_{0.05}$ CuO $_{4}$ single crystal ( $T_{c} \approx$ 10K). Incommensurate elastic magnetic peaks were observed in the low-tamperature tetragonal phase with the propergation vector parallel/perpendicular to in-plane Cu-O bond direction. The magnetic peak intensity normalized by the sample volume is approximately six times larger than that of the orthorhombic La $_{1.88}$ Sr $_{0.12}$ CuO $_{4}$ at low temperature.
