Abstract

Terbium tritelluride, TbTe₃, orders antiferromagnetically in three steps at T_N₁ = 6.7 K, T_N₂ = 5.7 K, and T_N₃ = 5.4 K, preceded by a correlation hump in magnetic susceptibility at T* ~8 K. Combining thermodynamic, i.e., specific heat C_p and magnetization M, and transport, i.e., resistance R, measurements we established the boundaries of two commensurate and one charge density wave modulated phases in a magnetic field oriented along principal crystallographic axes. Based on these measurements, the magnetic phase diagrams of TbTe₃ at H‖a, H‖b and H‖c were constructed.

Keywords: magnetic phase diagram; terbium tritelluride; thermodynamics; transport properties.
