Mössbauer study of a modified M-type Ba(Sr)-ferrite prepared by ion exchange

Structural, magnetic and dielectric properties of Zr–Cd substituted strontium hexaferrite (SrFe12O19) nanoparticles

“…While the coercivity of the samples decrease continuously with the Zr-Cd content. It has been reported that Cd 2+ ions occupy the tetrahedral site 4f 1 [32,33] while the Zr 4+ ions replace the iron ions from 2b at low substitution (x = 0.1) and at 4f 1 for higher substitution [34]. The electrons at 2b site have spin in upward direction while at 4f 1 have spin in downward direction as shown in Fig.…”
