“…Hexagonal ferrites are divided into five sub-categories based on their crystal structure and chemical formula: M-type (AFe 12 O 19 ), W-type (AFe 16 O 27 ), X-type (AFe 28 O 46 ), Y-type (AFe 12 O 22 ), Z-type (AFe 24 O 41 ), where A is the divalent cation like Ba 2+ , Sr 2+ , Pb 2+ , Ca 2+ [5][6][7]. Among these, M-type hexaferrite has gained more attention due to its distinguished properties like very high magnetic anisotropy, higher coercivity, higher corrosion resistance, high thermal and chemical stability [8][9][10][11]. Barium M-type (BaM) hexaferrite are ferrimagnetic materials with the chemical formula BaFe 12 O 19 and space group P6 3 /mmc.…”
