Here, we explored the magnetic properties of the low-dimensional Ba M 2 Si 2 O 7 (M = Cu, Co, and Mn) system using both experimental measurements and theoretical calculations. Magnetization, specific heat, and single crystal neutron diffraction measurements have been performed on single crystal Ba M 2 Si 2 O 7 . The spin structure was determined and a magnetic phase diagram with applied field along the b axis was constructed, which contains a spin flop transition around 6 T. Magnetization and specific heat measurements confirmed the presence of weak ferromagnetism in Ba M 2 Si 2 O 7 . Furthermore, we performed local-spin density approximation with on-site Coulomb energy (LSDA+U) calculations for the Ba M 2 Si 2 O 7 (M = Cu, Co, and Mn) system. Due to the first-principles calculations, the origin of the magnetic differences of the three materials is discussed.
