Structural and magnetic behaviour of aluminium doped barium hexaferrite nanoparticles synthesized by solution combustion technique

Influence of chromium substitution on structural and magnetic properties of BaFe12O19 powder prepared by sol–gel auto combustion method

“…More specifically substitution causes weakening of super exchange interaction of type Fe A 3+ -O-Fe B 3+ , leading to collapse of magnetic collinearity of the lattice. The decrease in saturation magnetization and remanence magnetization with substitution of Cr 3+ is closely agrees with the observations made for Al 3+ and Mn 3+ substituted barium hexaferrite prepared by glass ceramic technique and solution combustion technique [31,34,35].…”

Effect of Co-Ti Substitution on Magnetic Properties of Nanocrystalline BaFe12O19

“…As reported, the development of the barium ferrite compositions were substituted by Ba and (Sr) [6][7][8]. In order to understand the magnetic properties of BaFe 12 O 19 , the Fe was substituted by Al, Sn, NiSn, Ti, or Co [9][10][11][12][13]. Furthermore, the improvement of coercivity of BaFe 12 O 19 is needed to realize magnetic absorption materials such as microwave [14][15][16].…”

Effect of La3+and Ti4+Ions on the Magnetic Properties of Barium Hexaferrite Powders Synthesized Using Sol-Gel Method

“…The intrinsic magnetic properties of the barium hexaferrite can be changed by partial substitutions for Ba or Fe sites [6][7][8][9][10][11][12]. Previous works have shown that the magnetic properties of barium hexaferrite could be changed by substituting Ba 2+ with rare earth ions [10,[13][14][15].…”
