Query: Magnetism trends in doped Ce-Cu intermetallics in the vicinity of
  quantum criticality: realistic Kondo lattice models based on dynamical
  mean-field theory   The quantum critical point (QCP) in the archetypical heavy-fermion compound
CeCu$_6$ doped by Au is described, accounting for the localized $4f$-electron
of Ce, using realistic electronic structure calculations combined with
dynamical mean-field theory (DMFT). Magnetism trends in
Ce(Cu$_{1-\epsilon}$Au$_\epsilon$)$_6$ are compared with those in Co-doped
CeCu$_{5}$, which resides on the non-ferromagnetic side of the composition
space of one of the earliest rare-earth permanent magnet compounds,
Ce(Co,Cu)$_5$. The construction of a realistic Doniach phase diagram shows that
the system crosses over a magnetic quantum critical point in the Kondo lattice
in $0.2<x<0.4$ of Ce(Cu$_{1-x}$Co$_x$)$_5$. Comparison between Au-doped
CeCu$_6$ and Co-doped CeCu$_5$ reveals that the swept region in the vicinity of
QCP for the latter thoroughly covers that of the former. The implications of
these trends on the coercivity of the bulk rare-earth permanent magnets are
discussed.
