We present an x-ray magnetic circular dichroism (XMCD) study performed at the Co K edge and at the Er L2,3 edges in the Er1-xYxCo2 series. Our results indicate that both Er and Co magnetic sublattices order at the same temperature for all the investigated compounds. In the case of the Er0.6Y0.4Co2 compounds, XMCD data do not show the decoupling of the magnetic ordering for both Er and Co sublattices. Moreover, no experimental evidence of the occurrence of an inverse itinerant electron metamagnetism has been found for applied magnetic fields of up to μ0H=10 T. In addition, a nonzero magnetic moment is found at the Co sites in the case of the Er0.5Y0.5Co2 compound.
