Low temperature specific heat and electrical resistivity of UCu_4.5Al_7.5

The specific heat and electrical resistivity results are presented for UCu4.5Al7.5, 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−1 K−2. The other heavy fermion coefficients have also been calculated. The electrical resistivity data for UCu4.5Al7.5 include indications of strong crystal field effects
