abstract = {We report the discovery of incommensurate magnetism near
quantum criticality in CeNiAsO through neutron scattering
and zero field muon spin rotation. For T<TN1=8.7(3) K,
a second order phase transition yields an incommensurate
spin density with a wave vector k=(0.44(4),0,0). For
T<TN2=7.6(3) K, we find coplanar commensurate order
with a moment of 0.37(5)μB, reduced to $30\%$ of the
saturation moment of the |±12⟩ Kramers doublet ground
state, which we establish through inelastic neutron
scattering. Muon spin rotation in CeNiAs1−xPxO shows the
commensurate order only exists for x≤0.1 so we infer the
transition at xc=0.4(1) is between an incommensurate
longitudinal spin density wave and a paramagnetic Fermi
liquid.},
