Abstract

We have carried out elastic neutron scattering measurements on La_1.875Ba_0.075Sr_0.05CuO₄ single crystal (T_c≈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_1.88Sr_0.12CuO₄ at low temperature.
