Low temperature specific heat of UCo1-xOsxAl is investigated. Anomalous temperature dependences are observed for UCoAl and UCo0.998Os0.002Al, whose ground state locates near the quantum phase transition point of the itinerant-electron ferromagnetism. This suggests that an additional contribution to the electronic specific heat exists in these samples. The effect of conventional spin fluctuations cannot explain this behavior.
