Infinite ferrimagnetic AB(1)AB(2)-superlattice and A(n(A))B(n(B))-sandwich
structures, with constituents composed of various ferromagnets with equal t
hickness, are investigated using-1/2 Ising model in a linear cluster approx
imation. The phase diagrams and layered magnetizations indicate the existen
ce of 0-4-compensation phenomena which are discussed accounting for the rol
e of components thickness and interface couplings. (C) 1999 Elsevier Scienc
