Resumen:
de Haasvan Alphen oscillations were measured in lanthanum tritelluride (LaTe3) to probe the partially gapped Fermi surface (FS) 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. All three pockets are quasi-two-dimensional, consistent with expectations from band-structure calculations. Analysis of the field dependence of the oscillations is used to provide an estimate of the geometry of the reconstructed FS sections.
