Effect of zinc substitution on structural and magnetic properties of copper ferrite

Structural, electrical and magnetic properties of cadmium substituted copper ferrite by sol–gel method

“…7. Similar type of variation has been reported by Hankare et al [27]. The magnetic moment in Bhor magneton (lb) was calculated by using the formula [28]:…”

Structural phase transformation and hysteresis behavior of Cu-Zn ferrites

“…In Figure 7, it can be observed that the retentivity as well as hysteresis loop area increases at first and then decreases significantly. For the composition up to x = 0.4, the retentivity, hysteresis loss, and saturation magnetization are found to increase and then drop to a lower value for higher Zn concentration [47]. The increase in magnetization with Zn content up to x = 0.4 is due to the dilution of magnetization of the A sublattice by non-magnetic Zn 2+ ions, which can be explained on the basis of Neel's sublattice model [31].…”

Structural, electrical and magnetic properties of cadmium substituted nickel–copper ferrites

“…Vibrating sample magnetometer (VSM model 735 LakeShore) was used to measure the saturation magnetization and magnetic moment (in Bohr magneton) and can be estimated by using the following relation [6] …”

“…Cadmium the nonmagnetic divalent metal ion doped with nickel-copper ferrite is of interest in fundamental and applied research. An understanding of their properties as well as variety of applications such as transformers cores, antennas rods and in high quality filters is of special interest [6]. Polycrystalline ferrites have very good dielectric properties; it depends on method of preparation, type of additives and sintering conditions.…”
