The preparation of nonoriented as well as magnetically oriented specimens of 2MeO · 2BaO·‐6Fe 2 O 3 and 2MeO·3BaO·12Fe 2 O 3 is described. The MeO component is limited to NiO, ZnO, CoO, and CuO and mixtures of these in this discussion. The orienting apparatus and technique employed are briefly described. The magnetic permeability and loss as measured at 250 Mc is shown for many of these prepared compositions. The effect of the orienting magnetic field strength as well as firing temperature on the observed magnetic properties is discussed.
