Abstract
⺠The Fe3+ spin moment at 2a site undergoes switching in its direction with temperature. ⺠The weakening of superexchange interaction is caused by substitution of Ga ions. ⺠The selective local spin reversal is correlated with the broad ac susceptibility response. ⺠The PM-FM transition (at â¼325 K) is followed by the local spin reversal at lower temperature.
