Self-consistent band-structure calculations were performed for Ni/Ag b
ilayers to study important features of these materials. Using the Line
ar Muffin-Tin Orbital (LMTO) method, we carried out calculations for s
everal lattice parameters in order to obtain ground-state properties s
uch as equilibrium volume, bulk modulus and critical pressure of the N
i/Ag bilayers. The analysis of the density of states at equilibrium vo
lume gives a good description of the electronic and magnetic propertie
s of these bilayers. The results show a breakdown of the small magneti
c moment at Ni sites for certain critical lattice parameters.
