Magnetic properties of Fe/SnO2 amorphous multilayers prepared by rf sputtering are investigated. With the thickness ds of SnO2 layers fixed (5.0nm),the saturation magnetization Ms of the samples decreases with decreasing dm. This is due to the contributions from the dead-layer effect and the dimensional effect. On the other hand, when the dm of the samples is very thin, quasi-two-dimensional magnetic behavior is found. The Curie temperature TC decreases with decreasing dm, and coercivity Hc has a peak as dm varies. With the thickness of Fe fixed at 2nm, Ms increases with decreasing ds.
