Abstract:

Neutron powder diffraction was employed to study the pressure effect on the magnetic transition in the pseudobinary Laves-phase compound Er0.57Y0.43Co2 and to determine the magnetic moments of the Er-and Co-subsystems. Our studies reveal that the onset of long-range magnetic order for both the localized 4f (Er) and itinerant 3d (Co) electron moments appears at about the same temperature at ambient pressure. The pressure effect on Tc is found to be negative and equal for both sublattices, namely ∂Tc/∂p ∼ -0.4 K/kbar. The values of the magnetic moments of the Er and the Co ions are found μEr = 5.40 ± 0.15 μB/atom, μCo = 0.50 ± 0.07μB/atom and 5.35 ± 0.15μB/atom, 0.37 ± 0.09μB/atom, for p = 0 and 6 kbar, respectively. Our experimental results give evidence for short-range magnetic order formation at temperatures already above Tc and for a coexistence short-and long-range order below Tc down to 4 K.
