De Haas-van Alphen oscillations in the charge-density wave compound lanthanum tritelluride (LaTe_3)
arXiv:0805.0661 · doi:10.1103/PhysRevB.78.045123
Abstract
De Haas-van Alphen oscillations were measured in lanthanum tritelluride (LaTe_3) to probe the partially gapped Fermi surface resulting from charge density wave (CDW) formation. Three distinct frequencies were observed, one of which can be correlated with a FS sheet that is unaltered by CDW formation. The other two frequencies arise from FS sheets that have been reconstructed in the CDW state.
