( 0.01, ‐‐‐‐0.10) ferrites were synthesized by coprecepitation technique, using oxalate precursors. The x‐ray diffraction studies have revealed a single spinel phase for all the compositions. Lattice parameter [a] increases with increasing content. The magnitude of grain size (D) observed to be the same as reported by PJ. van der Zaag et al  for mono‐domains. The decrease in initial permeability is attributed to decrease in (i) grain size (D), (ii) decrease in saturation magnetization (Ms), and (iii) increase in magnetocrystalline anisotropy (K1). The variation in magnetocrystalline anisotropy is significant and becomes positive and large with the content of .
