Exchange bias (EB) behavior has been observed for multiferroic Fe $_{2}$ O $_{4}$ (=Y, Er, Tm, Yb, Lu and In). The materials with the small $^{3+}$ ions (=Tm, Yb, Lu and In) exhibit large EB fields ( $_sim^{>}$ 1 kOe) below 100-150 K. This property is rooted in a magnetically glassy state, arising from the competition between ferro- and antiferromagnetic domain interactions. In addition, the exchange bias field tends to be more enhanced for smaller $^{3+}$ ions. Hence, the EB is controlled by the substitution at the -site in this series.
