Electronic structure and magnetic properties of Cr/Sn multilayers

Electronic structure and magnetic properties of Cr/Sn metallic multilayers have been investigated using spin-polarized first principles tight-binding linear muffin-tin orbital (TB-LMTO) method within atomic sphere approximation (ASA). Calculations for an Fe/Cr multilayer have also been done for comparison. The experimentally observed reduced magnetic moment of thin Cr layer sandwiched between Sn or Fe layers has been explained from our band structure calculations. For Cr/Sn multilayer, self-consistent calculations have been done to determine the lattice relaxation for growth of multiple layers of Cr over one monolayer of Sn.
