TL;DR: Shubnikov-de Haas oscillations for two well-defined frequencies, corresponding, respectively, to areas of 0.8 and 1.36% of the first Brillouin zone, were observed in single crystals of Na(0.3)CoO2, suggesting the possibility that the periods are due to the reconstruction of the large Fermi surface around the Gamma point.
Abstract: Shubnikov–de Haas oscillations for two well-defined frequencies, corresponding, respectively, to areas of 0.8 and 1.36% of the first Brillouin zone, were observed in single crystals of Na0.3CoO2. The existence of Na superstructures in Na0.3CoO2, coupled with this observation, suggests the possibility that the periods are due to the reconstruction of the large Fermi surface around the ? point. An alternative interpretation in terms of the long sought-after ?g? pockets is also considered but found to be incompatible with existing specific heat data.
