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