Structural and magnetic Properties of TbZn-substituted calcium barium M-type nano-structured hexa-ferrites.

Highlights: [•] Tb–Zn substituted Ca0.5Ba0.5Fe12O19 samples exhibit single magnetoplumbite phase. [•] Lattice parameters a and c have increasing values. [•] Coercivity can be tuned at lower substitution level [•] Crystallites size was found in the range 18–25nm by TEM and by Scherrer formula. [•] These hexa-ferrites are suitable for microwave devices and magnetic recording media. [Copyright &y& Elsevier]
