The high-field magnetization process in the randomly diluted metamagnet Fe1−xMgxTiO3 has been investigated in single crystal samples with x≤0.3 by using dc magnetic fields of up to 300 kOe generated by a hybrid magnet. In contrast to the sharp metamagnetic transition along the hexagonal c axis observed in FeTiO3, the diluted compounds show a considerable smearing in the transition with increasing Mg concentration. When the field is applied along the a axis at 4.2 K, a sudden jump in magnetization occurs at 235 kOe in FeTiO3, while no anomaly is observed up to 300 kOe along the a* axis which is taken to be perpendicular to both c and a axes. The jump field is lower in the diluted compounds. For the sample with x=0.185 we have also observed an anomalous increase in magnetization along the a* axis at 270 kOe.
