Abstract
Magnetic and electronic properties of Fe N clusters embedded in antiferromagnetic BCC Cr near the sample surface as well as near the Fe/Cr interface have been studied within the framework of the periodic Anderson model. A distribution of the magnetic moments is determined self-consistently in the mean-field approximation taking into account the d-d-interaction in the first coordinate sphere of atoms. For all the investigated systems several magnetic configurations are found, and the energy of all configurations is calculated. The magnetic structure dependence on the size of clusters as well as on the spatial nonhomogeneity caused by surface or interface is investigated.
