We report neutron depolarization measurements of the suppression of long-range ferromagnetism and the concomitant emergence of magnetic irreversibilities and spin freezing in ${\mathrm{CePd}}_{1\ensuremath{-}x}{\mathrm{Rh}}_{x}$ around ${x}^{*}\ensuremath{\approx}0.6$. Tracking the temperature versus field history of the neutron depolarization, we find clear signatures of long-range Ising ferromagnetism below a Curie temperature ${T}_{\mathrm{C}}$ for $x=0.4$ โฆ
