Abstract
The temperature variation of low-field dc magnetization of the diluted antiferromagnet MnxMg1-xTiO3 has been measured. It has been found tha t the crossover phenomenon from random-field to spin-glass behavior oc curs near the percolation concentration X(P) = 0.57, which is experime ntally estimated. The origin of the appearance of the spin-glass-like behavior is discussed in relation to spin structures near the percolat ion concentration.
