Fe3BO6 shows no thermal hysteresis around the phase transition temperatureT SR=418 K; Fe2·88Ga0·12BO6 undergoes spin transition atT SR=403 K resulting in a reduction of theT SR. Both these features are different from the reported observations on α-Fe2O3. The two Fe3+ sites show difference in their magnetic interactions. Ga3+ replaces Fe3+ in a random manner.
