Elastic anomalies at the magnetic phase transitions of TbTe 3

Multiple magnetic-phase transitions and critical behavior of charge-density wave compound TbTe3

“…One magnetic transition is clearly seen at T N = 6.3 K, such a transition temperature is indeed very close to T mag1 suggested by Ref. 13 , which was evidenced in our ZF results.…”

“…It has raised the possibility that the LRMO is linked to the modulated structure in the CDW state, although further work is needed to investigate how the CDW and magnetic order may interact with each other. In a more recent work by Saint-Paul et al [13], through sound velocity and ultrasonic attenuation measurements, three successive transitions were suggested at T mag1 ∼ 6.5 K, T mag2 ∼ 5.8 K, and T mag3 ∼ 5.3 K. Despite that the lower two temperatures agree with [2] and [16], Saint-Paul et al indicated that the rst transition should occur at a higher temperature at around 6.5 K rather than 5.8 K.…”

“…3 The unique feature of RETe 3 compounds is the multiple CDW transitions at different temperatures [7][8][9][10][11][12] with the coexistence of long-range magnetic order (LRMO) below 10K. [13][14][15] TbTe 3 is the most studied compound from the family of RETe 3 . It has a CDW as a stable ground state at room temperature and undergoes two more CDW phase transitions observed at 41 K 3 and 5 K. 7 Notably, in TbTe 3 , a third CDW phase coexists with the magnetic order at ∼5 K. Ru et al 2 firstly revealed the multiple magnetic phase transitions in TbTe 3 by magnetization, heat-capacity, and electrical resistivity measurements.…”
