TmFe5Al7 is an interesting system from the viewpoint of competing exchange and anisotropy interactions. It is a ferrimagnet without compensation of the Tm and Fe sublattices and displays a very unusual phase diagram. At 64 K it undergoes an easy-axis-easy-plane spin-reorientation transition and becomes a commensurate antiferromagnet. In this phase, the Tm atoms do not carry magnetic moment, in agreement with the diffraction data collected previously at the D10 instrument (ILL). The ferrimagnetic order seems to be recovered at around 82 K. New data collected at the Cyclops instrument (ILL) has shown that another antiferromagnetic phase appears at around 70 K. This new phase is of incommensurate type. Furthermore, diffuse scattering is present in the entire antiferromagnetic domain and holds up to 95 K. Thus, the new incommensurate antiferromagnetic structure and the diffuse scattering within the antiferromagnetic phases deserve further detailed neutron scattering studies. This will allow to complete the phase diagram of this system and to explore the possible role of the antiferromagnetic short-range correlations in the collapse of the Tm magnetic moment region of the phase diagram.
