摘要：

Magnetization measurements are presented for the Fe3-xTi(x)O4 series in the range 0 less-than-or-equal-to x < 1. A new model of Fe3+(-)Fe2+ cation distribution is proposed based on saturation-magnetization data. A tilting of the easy magnetization axis away from the [001] direction was encountered at temperatures approaching 4.2 K for the titanium-rich specimens. Anomalies in the hysteresis parameter in the temperature range 40-100 K are reported. A distribution of Fe2+, Fe3+, and Ti4+ ions on tetrahedral and octahedral sites is proposed on the basis of saturation magnetization measurements, which differs to some extent from earlier models published in the literature.
