A series of Bi substituted yttrium iron garnet (Bi-YIG) nanoparticles with nominal formula of BixY3-xFe5O12 in which x varied in steps of 0.0, 0.25 and 0.5 are prepared by conventional method. Vibration sample magnetometer (VSM) at Room temperature (RT) shows saturation magnetization decreases from 27.4 to 25.2 (emu/g) as x value increases from 0.0 to 0.5. Room temperature 57Fe Mössbauer spectra are recorded for these series. The hyperfine field value for octahedral and tetrahedral of samples increases from 484 and 390 kOe to 491 and 397 kOe respectability, as Bi replaces Y in (BixY3-xFe5O12) atom with increasing x value. The effect of Bi3+ substitution for Y3+ on lattice constants, morphology and magnetic properties of pure YIG has been investigated. © Springer Science + Business Media B.V. 2008
