abstract = {We report on a neutron diffraction study of single-crystal
CePtAl3 complemented by measurements of the specific heat
under applied magnetic field. Below TN ≈ 3 K, CePtAl3
develops incommensurate antiferromagneticorder with a single
modulation vector k = (0.676 0 0). Residual magnetic
scattering intensity above TN and a broadening of the
specific heat anomaly at TN may be consistently described in
terms of a Gaussiandistribution of transition temperatures
with a standard deviation σ ≈ 0.5 K. The distribution of
TN may be attributed to the observation of occupational and
positional disorder between the Pt and Al sites consistent
withstructural information inferred from neutron
diffraction. Measurements under magnetic field reveal
changes of the magnetic domain populations when the field is
applied along the [0 1 0] direction consistent with a
transitionfrom cycloidal to amplitude-modulated magnetic
order ∼2.5 T.},
