Özet
This study contains information about the effect of V3+ vanadium doping on structural, morphological and magnetic properties of SrFe12-xVxO19 (x?=?0.00, 0.02, 0.04, 0.06, 0.08, 0.10) nanohexaferrites. Samples have been prepared via citrate sol-gel method and characterized. XRD and SEM analyses revealed the formation of M-type nanohexaferrites, wherein the particle size remained unaltered with the increase in vanadium contents. Mossbauer spectra disclosed the preferred occupation of V3+ ions at 4f1 tetrahedral site. Zero field (ZFC) and field cooled (FC) magnetization data in the temperature range of 2–400?K did not exhibit any blocking temperature, indicating mostly the ferromagnetic long-range ordering for the studied nanohexaferrites. Moreover, at low temperatures a spin glass behavior was observed. The ac-susceptibility showed a weakening in the Fe3+ - O2? - Fe3+ indirect exchange interactions with the increase in V3+ contents. Magnetic properties are argued in terms of the empirical rules of indirect exchange interactions taking into account the substitution of Fe3+ cations by V3+ ones in the preferred sites.
