Abstract:

Single-crystal neutron diffraction was employed to study the magnetic transition in the pseudobinary Laves-phase compounds Er1-xYxCo2 (x=0, 0.4) under external magnetic fields up to 4 T. The magnetic scattering amplitudes measured for the reflections to which either the localized 4f Er moment or the itinerant 3d Co moment solely contributes, give direct evidence that the onset of long-range magnetic order for both magnetic sublattices occurs at about the same temperature T(C)similar to35.9 and 17.0 K for x=0 and 0.4, respectively. The magnetic-susceptibility and specific-heat data, obtained on the same specimens, were also measured. In agreement with the neutron-diffraction data the macroscopic measurements showed no multiple phase transitions as opposed to earlier measurements on powder samples, which are presented and discussed as well.
