Abstract

Results of all-electron self-consistent spin-polarized band structure studies on a AgFe sandwich and on CuNi and PdAu coherent modulated structures are presented. For CuNi, modulations along left bracket 111 right bracket and left bracket 100 right bracket for different wavelengths and supercells up to 12 layers predict Ni moments to be reduced vs. f. c. c. Ni, but there are no 'dead' layers even in the most dilute system. Adjacent Cu layers acquire small magnetic moments, which may be measured by NMR. Increased exchange enhancements are found in PdAu and discussed in relation to the strongly exchange enhanced susceptibility previously observed in PdAu sandwiches by Brodsky and Freeman. For AgFe it is found that the Ag serves to greatly decrease the enhanced magnetism (to 2. 95 mu //B) found for the free Fe surface.
