Popis:	Platelike particles of BaFe 12 O 19 with epitaxially grown Fe 3 O 4 overlayers,6 x Fe 3 O 4 (1 − x )Ba Fe 12 O 19 , were prepared by a wet method. The structure was characterized by X-ray diffraction and TEM and SEM observations. Magnetic properties were studied by VSM and Moossbauer spectroscopic measurements. In order to study the magnetic behavior of very thin Fe 3 O 4 overlayers, Moossbauer measurements were applied to enrich samples, 6 x 57 Fe 56 Fe 2 O 4 (1 − x)Ba 56 Fe 12 O 19 , prepared from alkaline suspensions of Ba 56 Fe 12 O 19 particles and 57 Fe(OH) 2 .
