Abstract
We present ab initio calculations of the formation of magnetic moments in a large approximant to icosahedral Al-Pd-Mn quasicrystals. It is shown that large magnetic moments can form on a small number of Mn sites characterized by a loose coordination by Al atoms and some close Pd neighbors. d-d hybri dization is shown to play an important role.
