Magnetic properties of the charge density wave compounds RTe_3 (R=Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Tm)

摘要

The antiferromagnetic transition is investigated in the rare-earth (R) tritelluride RTe_3 family of charge-density wave (CDW) compounds via specific heat, magnetization, and resistivity measurements. Observation of the opening of a superzone gap in the resistivity of DyTe_3 indicates that additional nesting of the reconstructed Fermi surface in the CDW state plays an important role in determining the magnetic structure.
