NPD
Position structure was determined in the non-magnetic phase, at 15 K.
The difference pattern (1.8 K - 15 K) was refined with the relevant magnetic space group.
FM along the x direction. For larger substitutions of Si by Ag, the magnetic ordering changes and an AFM phase is reported (see entry #0.1030).
