Low Temperature Specific Heat and Electrical Resistivity of UCu sub 4.5 Al sub 7.5

The specific heat and electrical resistivity results are presented for UCu sub 4.5 Al sub 7.5 , a magnetically ordered nearly heavy fermion compound. The specific heat data do not indicate the expected anomaly characteristic for the magnetic order transition; only a very weak one was detected, which has been separated using a simple theoretical procedure. The electronic specific heat coefficient has been estimated to be 118 mJ mol exp --1 K exp --2 . The other heavy fermion coefficients have also been calculated. The electrical resistivity data for UCu sub 4.5 Al sub 7.5 include indications of strong crystal field effects. 14 ref.--AA
