The Fe3O4@HxMoO4nH2O nanolayers were synthesized on the solid surface for the rst time by Successive Ionic Layer Deposition (SILD) method with using an aqueous Fe3O4 suspensions and (NH4)2MoO4 solutions. The obtained nanolayers were investigated by XRD, SEM, EDX, FTIR spectroscopy and magnetization measurement techniques. SEM images showed that the
nanolayers formed by nanoparticles of size approximately 15{20 nm. The synthesized nanolayers exhibited superparamagnetic properties with the saturation magnetization value of 55 emu/g.
