Abstract :
In this paper evidence of a spin glass behaviour in FeSbO
4rutile from susceptibility and hysteresis loop measurements are presented. The spin glass transition has as a precursor effect a strong deviation of the Curie-Weiss law at

which indicates that strong antiferromagnetic spin correlations develop. It is argued that antisite Fe-Sb atomic ordering makes possible that nearest neighbours interactions compete with higher order magnetic interactions.
