“…XRPD and NPD also showed the presence of a glaserite-type Ba 3 MnSi 2 O 8 impurity phase (14.3 wt %), which we could not eliminate by varying the experimental synthesis conditions. The glaserite phase crystal structure was reported recently and does not order magnetically above 1.6 K, which is the lowest temperature reached in this experiment . Mn 3 O 4 was also found to be present at the level of 3.6 wt % from NPD.…”

“…The magnetometry peak observed at around 3 K is associated with the onset of magnetic ordering of the melilite phase. The glaserite phase does not show any magnetic ordering down to 1.6 K from previous neutron and magnetometry experiments and therefore does not contribute to this magnetometry peak. While the small amount of ferrimagnetic Mn 3 O 4 makes a significant ferrimagnetic contribution to the magnetic susceptibility plots at low temperatures, it should affect only a small percentage of the Curie–Weiss fitted magnetic moment due to the small weight percentage.…”

“…with the propagation vector k = (0,0,0). Ba 3 MnSi 2 O 8 was found to be paramagnetic down to the lowest experimentally achievable temperature of 1.6 K from previous studies and thus does not present any extra neutron diffraction peaks at these temperatures. Representational analysis performed with BasIreps for the Mn atoms located in the 2a (0, 0, 0) site followed by model testing unambiguously pointed to the irreducible representation Γ1 with a single basis vector.…”

Melilite-type Ba2MnSi2O7 was synthesized by a standard powder solid-state reaction route, and its magnetic properties were studied at low temperature. The magnetic structure was found to be C-type pointing along the c axis from neutron powder diffraction, which is different from the G-type ordering previously reported in all other 2-2-4-2 melilites with manganese as the B′-site transition metal. Ab initio (density functional theory) and magnetic dipole–dipole calculations were used to understand the magnetic structure by determining the spin supersuperexchange parameters as well as the relative influence of spin–orbit coupling and the magnetic dipole–dipole interactions.
