Claims

C1strongest claim

at 9.7 K, TbOF undergoes a structural phase transition accompanied by short-range magnetic correlations, in contrast to previously proposed long-range antiferromagnetic order. At lower temperatures, we observe two magnetic ordering transitions, consisting of incommensurate spin density waves and antiferromagnetic and ferromagnetic correlations. Furthermore, we observe metastable and hysteresis behavior below 2.0 K.

C2weakest assumption

The interpretation of neutron diffraction data as indicating short-range rather than long-range magnetic order at the 9.7 K transition, which depends on the resolution and analysis choices for distinguishing correlation lengths.

C3one line summary

TbOF shows a structural transition at 9.7 K with short-range magnetism, incommensurate spin density waves, antiferromagnetic and ferromagnetic correlations, and metastable behavior below 2 K.
