Structural and magnetic behavior of Pr-substituted M-type hexagonal ferrites synthesized by sol–gel autocombustion for a variety of applications

A series of M-type hexaferrites with chemical formula Ba0.25Sr0.75PrxFe12−xO19 (x=0.00, 0.05, 0.10, 0.15, 0.20, 0.25) were synthesized using sol–gel autocombustion method. The samples were pre-sintered at a temperature of 800°C for 3h and were finally sintered at 1200°C for 1h at the heating rate of...
