We have carried out elastic neutron scattering measurements on La₁.₈₇₅Ba₀.₀₇₅Sr₀.₀₅CuO₄ single crystal (Tc≈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 La₁.₈₈Sr₀.₁₂CuO₄ at low temperature.
