Description

A new uranium intermetallic compound, UFe2Zn20, was prepared and characterized by single-crystal X-ray diffraction, 57Fe Moessbauer spectroscopy and magnetization measurements. It crystallizes in the cubic Fd anti 3m space group (a=14.0998(9) A) and is isostructural with CeCr2Al20 (R=0.045, WR2=0.12). Moessbauer spectra, taken between 5 K and room temperature, consist of a symmetric quadrupole doublet with narrow lines, confirming an ordered structure with the iron on only one crystallographic site and showing no magnetic ordering transition above 5 K, in good agreement with magnetization measurements.
