Susceptibility and hysteresis measurements indicate that the system Fe3-xTixO4 forms only monodomains for 1.0 ≥ x≥ 0.3 irrespective of the physical grain size. Sharp susceptibility maxima, resembling those of spin glasses, are obtained for 1.0 ≥ x≥ 0.8, which could be attributed to the combined effect of decreasing anisotropy and the monodomains becoming superparamagnetic with increasing temperature.
