In this work we calculate the itinerant and localized magnetization curves
of the Laves phase intermetallic compound HoCo2 and discuss the nature of i
ts magnetic phase transition. The numerical results were calculated from th
e self-consistent solution of magnetic coupled equations obtained through t
he combination of functional integral methods with molecular field approxim
