The thermodynamic and transport properties of the Er1-xYxCo2 system were studied in the concentration range 0.0=x=1.0. In this system, the first-order magnetic phase transition observed in ErCo2 at TC2 K is related to the itinerant electron metamagnetism of the d subsystem (Co sublattice) driven by the onset of magnetic ordering within the Er sublattice. By employing magnetic, specific heat, thermal expansion, and resistivity measurements we show that in a limited concentration range xcr'
