Electrical conductivity of Co–Zr substituted hexagonal barium ferrites

Modification of the Magnetic Properties of Co₂Y Hexaferrites by Divalent and Trivalent Metal Substitutions

“…The physical properties were modified by the substitution of Ba ions and/or Fe ions by other metal ions. Specifically, Ba ions in these ferrites were substituted by Sr [8,70,71], Pb [72][73][74], and Ca [21,[75][76][77]. On the other hand, the effects of a large variety of substitutions for Fe ions on the structural and physical properties of hexaferrites were reported.…”

Synthesis and electromagnetic properties of La-doped Ni–Zn ferrites

“…Several techniques have been employed to prepare rare earth ions substituted ferrites, such as co-precipitation, sol-gel method, combustion synthesis, refluxing method, solid state method and hydrothermal method [15][16][17][18][19][20][21][22]. Extensive studies have been done to prepare rare earth-doped strontium and barium hexagonal ferrites [23][24][25]. However, few studies are available on the rare earth ions (La)-doped NiZn ferrites, which is the main subject in this research.…”

Magnetic Properties and Hyperfine Interactions in M-Type BaFe12-2xMoxZnxO19 Hexaferrites

“…Accordingly, the magnetic properties of the hexaferrites were modified by substituting Fe 3+ ions by a trivalent metal ion such as Al, Ga, In, Sc, As, Cr [10][11][12][13][14][15][16], or combinations of a tetravalent ion such as Ti 4+ , Ru 4+ , Zr 4+ , or Sn 4+ with a divalent ion such as Mn 2+ , Ni 2+ , Mg 2+ , Co 2+ , Zn 2+ , Ti 2+ or Sn 2+ [4,[17][18][19][20][21][22]. The structural and physical properties of the fabricated hexaferrite powders were found to be affected by the physical or chemical preparation method, as well as the experimental conditions such as stoichiometry, heat treatment, and binder additives [11,17,18,[23][24][25][26][27][28][29][30].…”
