New electronic orderings observed in cobaltates under the influence of misfit periodicities

A. Nicolaou, V. Brouet, M. Zacchigna +10

We study with ARPES the electronic structure of CoO2 slabs, stacked with rock-salt (RS) layers exhibiting a different (misfit) periodicity. Fermi Surfaces (FS) in phases with diffe…

Experimental study of the incoherent spectral weight in the photoemission spectra of the misfit cobaltate [Bi2Ba2O4][CoO2]2

A. Nicolaou, V. Brouet, M. Zacchigna +8

Previous ARPES experiments in NaxCoO2 reported both a strongly renormalized bandwidth near the Fermi level and moderately renormalized Fermi velocities, leaving it unclear whether…

Magnetoresistance scaling in the layered cobaltate Ca3Co4O9

P. Limelette, J. C. Soret, H. Muguerra +1

We investigate the low temperature magnetic field dependences of both the resistivity and the magnetization in the misfit cobaltate Ca3Co4O9 from 60 K down to 2 K. The measured neg…

Dual electronic states in thermoelectric cobalt oxide

Patrice Limelette, Sylvie Hebert, Herve Muguerra +2

We investigate the low temperature magnetic field dependence of the resistivity in the thermoelectric misfit cobalt oxide [Bi1.7Ca2O4]0.59CoO2 from 60 K down to 3 K. The scaling of…

Direct observation of strong correlations near the band insulator regime of Bi misfit cobaltates

V. Brouet, A. Nicolaou, M. Zacchigna +6

We present the first angle-resolved photoemission (ARPES) measurement of Fermi Surface in the "misfit" cobaltate [Bi2Ba2O4].[CoO2]~2. This compound contains the same triangular Co…
