Resum
We report here measurements of high field (H≤150 kOe) isothermal magnetization, dc and ac susceptibility, and Mossbauer spectroscopy of the exchange frustrated insulator SrCr8Fe4O19. 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 This unusual feature is interpreted as indicative of a transition where long range ferrimagnetic ordering has been replaced by a correlated spin‐glass phase with finite spin correlation length.
