The effect of non-magnetic Al3+ ions on the structure and electromagnetic properties of MgCuZn ferrite

Structural and Magnetic Properties of Cr-Co Nanoferrite Particles

“…Thus, the net value of K 1 decreases with the substitution of Cr 3+ ions in the samples. This behavior is in agreement with the observation noted by H. Bahiraei et al on Al doped MgCuZn ferrites [32]. The magnetic moment (n B ) per formula unit in Bhor magneton was calculated by using following equation [33].…”

“…A similar explanation for the decrease in Ms of coppersubstituted magnesium zinc ferrite has been provided by M. H. Zaki et al [23]. One can conclude that this technique's claimed saturation magnetization of the tested ferrites is superior to that of previous ceramic techniques [24] and auto-combustion routes [25]. This indicates that the employed coprecipitation technique has the potential to enhance the ferrite with higher saturation magnetization, making this ferrite significant throughout a broad range of frequencies.…”

“…However, Mg 2+ can also migrate from B-sites to A-sites depending upon heat treatment as discussed in the cation distribution of the studied ferrites in section one. One can conclude that the saturation magnetization of the investigated samples by this technique is better than that reported by other ceramic technique [45,49] and auto-combustion route [50]. That mean the used method(co-precipitation) has ability of improving the ferrite with higher saturation magnetization with low sintering time which make this ferrite important over a wide range of frequency.…”
