“…Magnetic materials in general in their nanocrystalline state have attracted considerable attention in recent years [20][21][22][23][24]. In this research, we have prepared Y 3 Fe 5Àx Al x O 12 (0pxp2) nanopowders by mechanochemical processing and subsequent heat treatments, and their magnetic properties have been investigated.…”

“…Since 1975, Wittekoek et al [5] reported that Faraday rotation effects can be further enhanced when yttrium ions in the garnet were partially substituted with bismuth ions. Bismuth substituted yttrium iron garnet (Bi-YIG) had received much attraction for their use in magneto-optical discs and also magneto-optical display devices [6,7]. Many efforts have been made by dispersing Bi-YIG particles in polymer to prepare modified polymer films and the modified films show good MO properties.…”

A series of Al substituted yttrium iron garnet (Al-YIG) nanopowders with nominal formula of Y 3 Fe 5−x Al x O 12 which x varied in steps of 0.0, 0.5, 1.0, 1.5 and 2.0 were prepared via mechanochemical processing. The samples were milled for 40 h in a high energy planetary mill and then calcined at different temperatures from 1,300 to 1,100 • C. X-ray diffraction patterns reveal that the structure of nanopowders are bcc and the garnet phase has been obtained after calcining. The average crystallite sizes are in the range of 24-45 nm, using Scherrer's formula. The lattice constant of the samples decreases by increasing Al concentration. To investigate the site preference of Al 3+ ions, room temperature 57 Fe Mössbauer spectra for the samples were recorded and analyzed. The hyperfine field values for octahedral and tetrahedral sites of the samples decrease by increasing x value. This decrease in magnetic hyperfine field reflects a reduction of the superexchange interaction by the progressive substitution of Al for Fe, which is also evident in the behavior of the magnetization and T C for the samples.
