Resumo

A comparative study of the magnetic properties of a palladium–cobalt alloy with an impurity content of up to 0.05 at. % was made using calculations based on the density functional theory and experimental methods. It was found that the alloys had ferromagnetic ordering, which depended on the impurity concentration. At very low concentrations, less than 1 at. %, the magnetic moment per impurity atom can reach 25 µB.

2. Fig. 1. View of the cell used in the modelling. There is one cobalt atom per 107 palladium atoms (the number of impurity atoms was increased to simulate a higher concentration). The ferromagnetic impurity polarises the matrix atoms in the vicinity. Palladium atoms with the highest magnetic moments are marked in the figure
