Cluster size effects in the magnetic properties of Fe${}_p$-Al${}_{q=1-p}$ alloys

João B. Santos-Filho, Alan V. Santos, Tatiana S. de Araujo Batista +1

A spin-1/2 Ising model, defined in the body centered cubic lattice, is used to describe some of the thermodynamic properties of Fe${}_p$-Al${}_q$ alloys, with $p+q=1$. The model assume…
