UCoAl is a 5f band metamagnet. The U1-xYxCoAl solid solutions were found to exhibit ferromagnetism for low Y content. The spontaneous magnetic moment reaches a maximum value of 0.22 μB for x = 0.06 and vanishes around x = 0.15. Tc is nearly constant (≈14 K) for x- 0.02-0.08. The unit-cell volume increases linearly with x up to 0.4.
