## Abstract The ferrite samples of Ni~0.7−__x__~Mn~__x__~Zn~0.3~Fe~2~O~4~ (where __x__ = 0.0–0.7 in steps of __x__ = 0.1) were synthesized by a sol–gel autocombustion method using nitrates of respective metal ions. The synthesized samples were annealed at 600 °C for 4 h. The phase purity of the sam
The dielectric and magnetic properties of Mg incorporated Ni-Zn spinel ferrites have been investigated. Ni 0.5 À x Zn 0.5 Mg x Fe 2 O 4 ferrites have been prepared by sol-gel auto-combustion technique. The as prepared ferrites were annealed at 673, 873 and 1073 K. The X-ray diffraction studies revea
