The influence of impurities on the electronic structure and magnetic properties of iron .2. 2p- and 3p-impurities in amorphous iron

The results of the first principles' calculations of the electronic structure and magnetic properties of 2p- and 3p-impurities in ferromagnetic amorphous iron, obtained by the self-consistent tight-binding LMTO-recursion method, are presented. The calculations were made in the single-site approximation for an <<average atom>>. The peculiarities of the electronic structure of impurities caused by the structural disorder are considered. The role of impurities in stabilization of ferromagnetic state of amorphous Fe is discussed on the basis of calculations of changes of effective exchange interactions parameters for nearest to impurities neighbour host atoms.
