- Аннотация: n this paper the charge density wave (CDW) and magnetic ordering for the high-pressure phase of TbGe2.85 with the AuCu3 structure have been studied by means of electrical resistivity and neutron powder diffraction at pressures up to 3 and 5 GPa, respectively. The electrical resistivity measurements showed that the charge density wave transition temperature TCDW decreases with increasing the external pressure and the CDW transition in TbGe2.85 is suppressed at P≥2.6GPa. The Néel temperature TN is approximately independent of the pressure. The neutron powder diffraction at low temperatures and high pressures reveals the appearance of the second magnetic commensurate phase at P=1.2GPa with wave-vector k=(1/2,0,0). The calculation of the electronic structure of the TbGe3 (AuCu3-type structure) compound was also performed. The high value of the electronic states at the Fermi level confirms the instabilities of the stoichiometric compound TbGe3.
