  The relevant approximate spontaneous magnetization relations for the
simple-cubic and body-centered-cubic Ising lattices have recently been obtained
analytically by a novel approach that conflates the Callen--Suzuki identity
with a heuristic odd-spin correlation magnetization relation. By exploiting
this approach, we study an approximate analytic spontaneous magnetization
expression for the face-centered-cubic Ising lattice. We report that the
results of the analytic relation obtained in this work are nearly consistent
with those derived from the Monte Carlo simulation.
