Magnetostriction of Ni-Zn ferrites containing cobalt

Origin of magnetocapacitance in chemically homogeneous and inhomogeneous ferrites

“…On the other hand, rhombohedral distortion in Co-substituted nickel-zinc ferrite has been reported. 25 As the present material is charge neutral, the possibility of charge ordering has been eradicated. Hence, to investigate this further, we obtained a slow scan XRD pattern.…”

Magnetoelectric properties of Gd and Nd-doped nickel ferrite

“…It has been reported that, partial substitution of Fe by Cr in Cu ferrite leads to tetragonal distortion [3] with c/a41, owing to Jahn-Teller effect. Rhombohedral distortion in Co-substituted Ni-Zn ferrite has been reported [4].…”

“…Cobalt, Iron and nickel ferrites are some of the centrosymmetric magnetic materials [1][2][3][4][5] and have inverse spinel structure. In the inverse spinel structure, the tetrahedral (A) sites are occupied by the Fe 3+ ions and the octahedral sites (B) are occupied by the divalent metal ions (M 2+ ) and Fe 3+ , in equal proportions.…”

Tailoring the temperature characteristics of the magnetic permeability of NiZn ferrites

“…Most of the material specifications for specific transformer applications require very low temperature factors, usually below 4 Â 10 À 6 values. In many of the above applications, cobalt-doping is being applied, in order to modify the magnetocrystalline anisotropy of the ferrite and adjust the resonance to higher frequencies [6].…”
