Fermi surface nesting and charge-density wave formation in rare-earth tritellurides

The Fermi surface of rare-earth tritellurides sRTe3d is investigated in terms of the nesting-driven chargedensity wave formation using positron annihilation and first-principles linear muffin-tin orbital calculations. Fermi surface nesting is revealed as a strong candidate for driving charge-density wave formation in these compounds. The nesting vector obtained from positron annihilation experi...

Hidden fermi surface nesting and charge density wave instability in low-dimensional metals.

The concept of hidden Fermi surface nesting was introduced to explain the general observation that certain low-dimensional metals with several partially filled bands exhibit charge density wave (CDW) instabilities, although their individual Fermi surfaces do not reveal the observed nesting vectors. This concept was explored by considering the Fermi surfaces of the purple bronze AMo(6)O(17) (A =...

Spin density wave order, topological order, and Fermi surface reconstruction

Magnetic properties of the charge density wave compounds

The antiferromagnetic transition is investigated in the rare-earth (R) tritelluride RTe3 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 DyTe3 indicates that additional nesting of the reconstructed Fermi surface in the CDW state plays an important role in determining ...
