The isothermal magnetization and Mossbauer spectroscopy results are consistent with a ferrimagneticlike transition at TC≊250 K. Low field dc and ac susceptibility measurements reveal a reentrant spin‐glass transition at low temperature but they fail to show any anomaly at the nominal Curie temperature TC. This unusual feature is interpreted as indicative of a transition where long range ferrimagnetic ordering has been replaced by a correlated spin‐glass phase with finite spin correlation length.3 p.application/pdfeng(c) American Institute of Physics, 1988Espectroscòpia MössbauerPropietats magnètiquesFerritaVidres de spinFísica de l'estat sòlidMössbauer spectroscopyMagnetic propertiesFerriteSpin glassesSolid state physicsinfo:eu-repo/semantics/article43735info:eu-repo/semantics/openAccess
