A model of magnetic interaction of CrO2 and Pd hexagonal layers in PdCrO2 is proposed. Since Cr-O-Pd bridges do not provide an interlayer magnetic coupling in case of a 120 magnetic ordering, a direct exchange interaction between magnetic chromium ions and conductive palladium layers is assumed. It is shown that this interaction leads to a novel state of itinerant electrons (skew bands). It is characterized by abnormally high conductivity at low temperatures due to strong suppression of umklapp…

From basic properties to the Mott design of correlated delafossites

The natural-heterostructure concept realized in delafossites highlights these layered oxides. While metallic, band- or Mott-insulating character may be associated with individual layers, inter-layer…
