Dependencia de la Temperatura de Compensación en Modelos de Multicapas Ferrimagnéticas de tipo $3(S_{1-x} σ_x)/σ$

We investigate numerically the behavior of the compensation temperature, $T_{comp}$, in ferrimagnetic multilayer in the type $3(S_{1-x} σ_x)/σ$ with respect to the increase of the spin concentration $σ_x$, which are randomly distributive in a mix of spins $S = 0, \pm 1$ and $σ= \pm 1/2$, 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 $σ_x$ 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.
