In this paper, we simulate the A / Ag (A=Fe, Co and Ni) bimetallic nanomaterials using Density Functional Theory (DFT) with Dmol3 code to calculate magnetic moments, lattice constants and binding energies of various systems which include three-dimensional (bulk), two-dimensional (thin film), one dimensional (chain) and zero dimensional (nanoparticle) systems and compare the findings with the ones of the pure materials of the same size.
