The magnetic properties of the polycrystalline CeNi₄Mn_{y}Al_{1-y} compounds have been investigated combining AC susceptibility, field-cooled and zero-field-cooled DC magnetization and magnetic relaxation measurements. The X-ray diffraction measurements showed that the group CeNi₄Mn_{y}Al_{1-y} is isostructural and crystallizes in the CaCu₅-type structure (P6/mmm). For 0 < y < 1 irreversible magnetism, long-time magnetic relaxation effect and evident upshift of the AC susceptibility peak with increasing frequency are observed at low temperatures. The spin-glass-like behaviour originates from disorder due to the statistical occupation of the 3g site. Using our data we have constructed the tentative phase diagram.
