Crystal chemistry, Rietveld analysis, magnetic and microwave properties of Cu-doped strontium hexaferrites

Copper-doped M-type strontium hexaferrite particles of composition SrCu x Fe 12- x O 19 ( x = 0.0 to 1.0) through co-precipitation were synthesized. The structure of a crystal, morphology, microwave absorption, and magnetic properties of the materials were investigated in detail with Cu concentrati...

Beschreibung
Zusammenfassung:	Copper-doped M-type strontium hexaferrite particles of composition SrCu x Fe 12- x O 19 ( x = 0.0 to 1.0) through co-precipitation were synthesized. The structure of a crystal, morphology, microwave absorption, and magnetic properties of the materials were investigated in detail with Cu concentration. X-ray patterns indicated a single M-type phase for hexaferrites with x ≤ 0.6, while impurity phase in addition to M-type phase has been observed with x > 0.6. The obtained results have been explained based on composition, magnetic exchange interaction, and microwave phenomena.
