Abstract

We report a neutron diffraction study of the magnetic phase transitions in the charge-density-wave (CDW) TbTe $_3$ compound. We discover that in the paramagnetic phase there are strong 2D-like magnetic correlations, consistent with the pronounced anisotropy of the chemical structure. A long-range incommensurate magnetic order emerges in TbTe $_3$ at $T_{mag1}$ = 5.78 K as a result of continuous phase transitions. We observe that near the temperature $T_{mag1}$ the magnetic Bragg peaks appear around the position (0,0,0.24) (or its rational multiples), that is fairly close to the propagation vector $(0,0,0.29)$ associated with the CDW phase transition in TbTe $_3$ . This suggests that correlations leading to the long-range magnetic order in TbTe $_3$ are linked to the modulations that occur in the CDW state.
