The curve along the easy [001] direction exhibits a distinct anomaly at Hcr=39 T, where the magnetization exhibits a stepwise rise from Ms to Mflip=40.6 mB/f The observed transition from the ferrimagnetic ground state to the saturated spin-flip state with parallel orientation of the sublattice moments is unusual for 3d-4f intermetallics because it does not proceed via an intermediate angled-sublattice state. Rather, a collinear remagnetization of the Tm sublattice takes place: as the applied magnetic field grows, the Tm moments disorder at first, reaching a fully disordered paramagnetic state at H=Hcr, then they order magnetically in the opposite sense.
