✦ Synopsis

The magnetism is investigated for pseudomorphic monolayers of (V, Cr and Mn) and their substitutional c(2 • 2) alloyed structures adsorbed on Pt(0 0 1) semi-infinite surfaces using the semiempirical tight-binding method. Vanadium pseudomorphic monolayer exhibits a c(2 • 2) magnetic ordering, whereas Cr and Mn overlayers exhibit both c(2 • 2) and p(1 • 1) magnetic structures. The substitutional alloyed overlayers exhibit ferrimagnetic structures that leads to appreciable net surface magnetization.
