This study explores the creation of soft–hard ferrite composites of NiCuZn‐ and strontium hexaferrites ferrite using sol‐gel autocombustion and physical mixing, revealing the coexistence of soft cubic spinel and hard hexagonal phases. Changes in lattice parameters, grain sizes, and strain are observed for different compositions, significantly impacting
