Query: Unconventional magnetism and electronic state in frustrated layered
  system PdCrO$_2$   First-principles calculations and a model consideration of magnetically
frustrated layered material PdCrO$_2$ are performed. The results on the
exchange parameters are in agreement with the experimental data on the
Curie-Weiss temperature ($\theta$). We show that experimentally observed strong
suppression of the N\'eel temperature ($T_N$) in comparison with the
Curie-Weiss temperature is due to three main factors. First, as expected, this
is connected with the layered structure and relatively small exchange
interaction along the $c$ axis. Second, deformation of the ideal in-plane
120$^{\circ}$ magnetic structure is crucial to provide finite $T_N$ value.
However, these two factors are still insufficient to explain low $T_N$ and the
large frustration factor $|\theta|/T_N$. Thus, we suggest a scenario of an
exotic non-Fermi-liquid state in PdCrO$_2$ above $T_N$ within the frameworks of
the Anderson lattice model, which seems to explain qualitatively all its main
peculiarities.
