Abstract
We have successfully synthesized single crystals of using a flux method, and we present a comprehensive study of the physical properties using magnetic susceptibility, specific heat, electrical resistivity, thermoelectric power, and x-ray absorption spectroscopy (XAS) measurements. undergoes two close antiferromagnetic transitions at respective temperatures of K and K, which are associated with the moments. Both transitions are suppressed upon applying a field, and we map the temperature-field phase diagrams for fields applied parallel and perpendicular to the easy axis. XAS measurements reveal that the Eu is strongly divalent, with very little temperature dependence, indicating the localized nature of , with a lack of evidence for heavy-fermion behavior.
