We investigated the magnetic properties of thin film samples with different number of layers stacked by the LB technique. The film samples showed a magnetically complex behavior in low temperature region, which is insufficiently explained by the idea of the homogenous dipole interaction field analogous to the demagnetizing field. The film thickness dependent behavior is discussed in terms of a picture of the magnetic viscosity which is realized in reentrant spin glass materials.
