Magnetic structure with all atoms

Magnetic structure with only magnetic atoms

• NSD
• Non-standard parent setting Pmmn, with origin 1 choice.
• So-called phase B observed under a (010) stress of 440 MPa. At zero stress an incommensurate phase is observed.
• The space group Pmmn (N. 59), resulting from the strain caused by the stress has been considered the parent symmetry, the space group at zero stress being however P4/nmm (N. 129).
• The Ce positions in the mcif file provided as supplemental material of the article slightly differ from those that can be derived from the Pmmn structure reported in the article for the same conditions of temperature and stress. Here, the Ce positions in this mcif file have been assumed to be correct, but have been completed with the positions of the non-magnetic atoms resulting from the Pmmn structure reported in the article.

• 1k magnetic structure
• Two 2-dim irreps along a special direction have as epikernel the observed MSG and the reported spin arrangement requires equal magnitudes for basis vectors of these two irreps. Therefore, both irreps can be considered primary.
• Inversion center broken by the magnetic ordering. Polar along z.
• Four non-trivial domains are to be expected, two of them with the rows of non-zero and zero magnetic moments interchanged.
