摘要：

We present the results of magnetic susceptibility, electrical resistivity and Mossbauer effect measurements performed on two crystallographic structures of UFeAl: high-temperature (HT) and low-temperature (LT) phases, i.e. MgZn2- and Fe2P-type structures respectively. The exchange-enhanced Pauli susceptibility and spin-fluctuation characteristics of the temperature dependence of the electrical resistivity of UFeAl are almost independent of the type of crystal structure. Fe-57 Mossbauer spectra of both crystallographic phases of UFeAl, recorded in the temperature range 10-295 K, consist of two symmetric quadrupole doublets for each crystal structure associated with the non-equivalent crystallographic positions of Fe. The Debye temperatures for the HT and LT structures of UFeAl were also estimated.
