A model to calculate self-consistently the local magnetic moment and the magnetic hyperfine field Bhf at the nuclei of 119Cd in RAl2 (R = rare earth metal), where the impurity occupies the Al site, is proposed. The local magnetic moment and the magnetic hyperfine field Bhf have two contributions each: one arising from the 4f electrons of the R ions and the other arising from the 3p electrons of Al. Our results are in good agreement with the experimental data.
