Abstract

The angle-resolved photoemission spectroscopy (ARPES) study of Na _0.7CoO₂ crystals was presented. The crystals were grown by the flux method and measurements performed at the Advanced Light Source Beamlines 12.0.1 and 7.0.1 using a Scienta analyzer. Despite some similarities with the cuprates, the cobaltates show their own unique set of anomalous properties. The results show a strongly renormalized quasiparticle band, a hole-type Fermi surface, a large Hubbard U and a small Fermi velocity.
