“…6). Beside the stationary band, the four dispersive bands characterize the band structure of KMo 6 This new determination of the band structure of KMo 6 O 17 significantly differs from the first determination [12], but it seems to be quite similar to the band structure of NaMo 6 O 17 [8]. Our results show some differences with the theoretical band structure proposed by Whangbo, Canadell et al [7].…”

“…The electronic properties of molybdenum purple bronze KMo 6 O 17 have been widely investigated and have demonstrated the low dimensionality of this compound, the occurrence of a Peierls transition close to 110 K and the existence of a charge density wave at low temperature [1,2]. Therefore KMo 6 O 17 is a reference compound for quasi two-dimensional systems that develop charge density wave instabilities.…”

“…The charge density wave vector is commensurate in the (0 0 1) plane: q ¼ 1 2 a * , and the charge density wave develops in three directions at 120°from each other, due to the hexagonal symmetry of the structure in the (0 0 1) plane. The low temperature state of KMo 6 O 17 exhibits specific properties, like giant magnetoresistance and high magnetic field induced transitions [6].…”

“…It is a quasi-2D metal with a trigonal structure including MoO 6 octahedra layers separated by K + ions and MoO 4 tetrahedra [14][15][16][17][18][19][20][21][22]. Its Fermi surfaces (FSs) consist of two electron pockets at and one hole pocket at L for the partially filled d bands with no apparent nesting character in the first Brillouin zone [14,15].…”

Longitudinal magnetoresistivity ρ xx (B) and Hall resistivity ρ xy (B) of KMo 6 O 17 single crystals have been measured up to 60 T in a pulse magnet. Remarkable and unusual features at characteristic magnetic fields were found in both ρ xx (B) and ρ xy (B), which were attributed to Fermi surface reconstructions caused by field-induced density-wave transitions. To understand these transitions in detail, we analyzed ρ xx (B) and ρ xy (B) based on a multiband model. This model successfully described the experimental results, revealing that charge carriers are increased significantly at these transitions with increasing magnetic field as a result of the Fermi surface reconstruction. In particular, the charge carriers are increased by two orders of magnitude at B osc = ∼40 T, above which a quantum oscillation emerges in both ρ xx (B) and ρ xy (B). This strongly suggests that the field-induced quantum oscillation is closely related with the induced charge carriers.
