The lightly hole-doped system CeOs${}_{1.94}$Re${}_{0.06}$Al${}_{10}$ has been studied by muon spin relaxation and neutron diffraction measurements. A long-range antiferromagnetic ordering of the Ce sublattice with a substantially reduced value of the magnetic moment $0.18(1){\ensuremath{\mu}}_{B}$ has been found below ${T}_{N}=21$ K. Similar to the undoped parent compound, the magnetic ground state …
