The present study focuses on the investigation of Cu-Cr co-substituted M-type barium hexaferrites, specifically for its potential use in lossless low-frequency applications. The research examines several aspects of these materials, including their dielectric properties, surface morphology, thermal behavior, magnetic properties, and Raman spectroscopic features. Several samples of M-type BaCuxCrxFe12-2xO19 were synthesized using a green technique that included the use of an extract derived from mentha plants. After being subjected to a temperature of 1100°C, the samples were subjected to several analytical techniques including structural analysis, thermal analysis, magnetic analysis, Raman spectroscopy, and low frequency dielectric testing. The X-ray diffraction (XRD) results revealed the presence of two distinct phases, namely the M-phase and the secondary BaFe2O4. The observed samples had a characteristic of being hard magnetic, characterized by the presence of multi-domain structures. Additionally, the use of Raman spectroscopy provided confirmation that the Fe ions had effectively substituted the Cu and Cr ions. https://lnkd.in/dFFCTRp4 #HexaferriteResearch #GreenSynthesis #MagneticMaterials
