摘要：

We have grown samples of (Mn,Zn,Fe)(3)O(4) on (100) Si substrates that are photomagnetic at room temperature. The samples were grown with cation concentrations containing zero crossings of the first order anisotropy constant K(1) near room temperature. Photomagnetic measurements with and without HeNe illumination show an increase in initial magnetization up to 8.1% at 100 Oe due to a significant increase in the initial permeability of these samples. This photomagnetic effect is explained by an intervalence charge transfer occurring when K(1) is small. The magnitude of the photoinduced magnetization increases with decreasing nanocrystallite size.
