• We have investigated the magnetization process of Fe_xMn_<1-x>TiO_3 (0.25≤x≤0.80) with exchange frustrations at 1.4 K. Applied fields H were swept in the modes A and B (see the text), and the sweep-rate R of H was changed from 0.05 T/s to 0.375 T/s. We have shown that the magnetization process changes systematically with x and R. The most important and distinguishing phenomena are the anomalous jump-up and jump-down of magnetizations M. The mechanism of the jump-up of M is discussed on the basis of the properties of the spin-glass state.Fe_xMn_<1-x>TiO_3spin-glassmagnetization processhysteresis loopsweep-rate
