✦ Synopsis

High field magnetizations up to 100 T, lattice constants and electronic specific heat coefficients have been measured for the Laves phase Lu(Col-~Mx)2 (M = Ga, Sn and Si) compounds which exhibit itinerant electron metamagnetism for small x. The lattice constant increases with increasing x for M = Ga or Sn, while it decreases linearly in the case of M = Si. The metamagnetic characteristics strongly depend on the substitutional element M. The critical field for the metamagnetic transition decreases with increasing x for M = Ga and Si, whereas it remains constant around 40 T above x = 0.06 for M = Sn. The magnetization jump due to the transition increases for M = Sn and rapidly decreases for M = Si. The different characteristics may result from the difference in the shape of the density of states modified by the substitutional element.
