  We investigate numerically the behavior of the compensation temperature,
$T_{comp}$, in ferrimagnetic multilayer in the type $3(S_{1-x}
\sigma_x)/\sigma$ with respect to the increase of the spin concentration
$\sigma_x$, which are randomly distributive in a mix of spins $S = 0, \pm 1$
and $\sigma = \pm 1/2$, with ferromagnetic interaction between spins of the
same type, and antiferromagnetic interaction for spins of different type. We
have found that $T_{comp}$ decrease slowly with the increase of $x$, until
$\sigma_x$ represent a little more than 40\% of the spin mixture. For higher
concentration values $T_{comp}$ drops abruptly and disappears, as predicted by
experimental result.
