;
NPD
Position structure is not given. Here one at room temperature retrieved from the ICSD is used.
This the first magnetic phase observed when lowering the temperature. Below 5.4K a more complex 2k magnetic ordering is reported (see #2.87).

_active_magnetic_irreps_details
;
1k magnetic structure
k-maximal magnetic symmetry
The active irrep has two k-vectors. A 2k-model involving both k-vectors of the irrep, which could equally fit the data is not discussed.
