“…The M s of SrPr 0.5 Fe 11.5 O 19 and BaCo 2 Pr 0.5 Fe 15.5 O 27 is lower than that of SrFe 12 O 19 and BaCo 2 Fe 16 O 27 , probably because of the smaller magnetic moment of Pr 3+ and the effect of Pr 3+ on the Fe–O–Fe super exchange interaction. 7,47 The M s of all composite samples is higher than that of SrPr 0.5 Fe 11.5 O 19 or BaCo 2 Pr 0.5 Fe 15.5 O 27 , possibly because the magnetic exchange coupling increases the M s . 48…”

“…Among all the magnetic oxide materials, Barium hexaferrite (BHF) is drawn attention due to its high saturation magnetization (70 Am 2 kg −1 ), large coercive field (474 kAm −1 ), and high corrosion resistance property [1]. There are many ways to improve the magnetic properties of BHF by doping a suitable element in Ba or Fe sites, modifying synthesis methods, and making composites [2][3][4][5][6][7][8]. The magnetic interaction between two magnetic components in magnetic composites has been explored by researchers in the recent past.…”

Magnetic behavior of BaFe 12 O 19 + (x) CuFe 2 O 4 (with x=1, 2, and 4) has been explored. These composites were prepared by the standard sol-gel route. X-ray diffraction, Field Emission Scanning Electron Microscopy, and Transmission Electron Microscopy techniques were employed to characterize the composites. The magnetic interaction between CuFe 2 O 4 and BaFe 12 O 19 particles in the composite has been studied by recording the M-H hysteresis loops by employing the Vibrating Sample Magnetometer technique. The role of copper ferrite in the BaFe 12 O 19 + CuFe 2 O 4 composite has been explored. It is interesting to note that the BaFe 12 O 19 + CuFe 2 O 4 (i.e. x =1) composite shows the maximum magnetic parameters (Ms , Hc , and (BH)max ) among all the composite samples under study. Hence, this composition has been investigated extensively by annealing at different temperatures to optimize its magnetic properties. The BaFe 12 O 19 + CuFe 2 O 4 composite annealed at 1000 °C exhibits the maximum energy product (BH)max and saturation magnetization (Ms ). The magnetic interaction between two different magnetic phases in the composite has been explored by using the Henkel plot study with the help of isothermal remanent magnetization (IRM) and direct current demagnetization (DCD) M-H curves. The exchange coupling between soft and hard magnetic phases in the composite is also examined by the derivative of magnetization with the magnetic field.
