The discovery of magnetoelectric (ME) effects caused by a cycloidal spin order has initiated an intense research on new class of ME materials. Among them one interesting class of materials is the hexaferrites such as Y-type (A $_{2}$ Me $_{2}$ Fe $_{12}$ O $_{22}$ : Me=transition metal), M-type (AFe $_{12}$ O $_{19}$ : A=Pb, Ca, Sr, Ba, etc.), where types of elementary blocks and their stacking order are different. These materials show a variety of complex magnetic ordering. In this presentation recent neutron diffraction experiments on multiferroic hexaferrites performed at the JRR-3 Neutron Science Facility of Japan Atomic Energy Agency (JAEA) are reported.
