“…In recent years, the ferrites have been known as great practical materials as well as the special class of magnetic compounds [1][2][3][4][5][6][7][8][9][10]. Because of their significant dielectric, magnetic properties, they are used in wide ranges of applications at different fields of technology (energy, refrigeration, and health) [11][12][13][14][15][16][17][18][19].…”

In this work, we prepared Co 1-x Mn x Fe 2 O 4 (CMFO) ferrites at different levels of doping x = 0.0, 0.1, 0.3, 0.5 and 0.7 using flash auto-combustion method, aiming to obtain promising results more than CoFe 2 O 4 ferrite prepared by other methods. The results show an increase in lattice constant of CMFO with Mn content. In addition, there are many intra-granular pores and significant fusion of the small grains into larger grains. The dielectric properties of CMFO ferrites are enhanced with Mn content. Furthermore, saturation magnetization (M S ) and remanent magnetization (M r ) of CMFO are improved slightly with Mn content up to x = 0.1 and then decrease with higher Mn content. The coercivity (H C ) of CMFO ferrite decreases with Mn content until it reaches minimum value of 971 Oe for level of Mn substitution x = 0.5; on further Mn content (X = 0.7), it is observed that H c increases to 1249 Oe. In comparison to previous works, H C (x = 0) and M S and M r for our sample (x = 0.1) are significantly more than corresponding values obtained for CoFe 2 O 4 ferrite prepared by other methods.
