The study explores the structural, thermal, magnetic, surface morphology, Raman spectroscopic, and dielectric properties of Cu-Cr co-substituted M-type barium hexaferrites for lossless low-frequency applications. Using a green synthesis approach with mentha leaves extract, a series of M-type BaCuxCrxFe12-2xO19 samples were synthesized. The samples were heated to 1100°C and characterized for structural, thermal, magnetic, Raman spectroscopic, and low frequency dielectric studies. XRD results revealed the formation of M-phase and secondary BaFe2O4 phase. Raman spectroscopy showed successful replacement of Cu and Cr ions with Fe ions, and the samples showed a hard magnetic nature with multi-domain structures.
