摘要：

We have performed Monte Carlo simulations on the mixed highly frustrated K2CuxMn1-xF4 and FexMn1-xTiO3 systems. Transitions of random systems with well-established universality classes are obtained. This study allows us to investigate mainly the usual and re-entrant spin glass and criticality associated with these states. The ratio x of substitution (or dilution) is found to have a large influence on the nature of this criticality.
