We report a chemical substitution-induced ferromagnetic quantum critical point in polycrystalline ${\mathrm{Ni}}_{1\ensuremath{-}x}{\mathrm{Rh}}_{x}$ alloys. Through magnetization and muon spin relaxation measurements, we show that the ferromagnetic ordering temperature is suppressed continuously to zero at ${x}_{\mathrm{crit}}=0.375$ while the magnetic volume fraction remains 100% up to ${x}_{\mathrm{crit}}$, pointing to a second order transition. โฆ
