Enhanced magnetic transition temperatures are demonstrated in 50 nm thick (001)‐oriented (BiFeO 3 ) m /(BiMnO 3 ) m (BFO/BMO) superlattices (SL). Highly strained ultra‐short SLs showed a magnetic transition, T C2 , up to ≈410 K as a result of ferrimagnetic interaction between BFO/BMO. All SL showed a new ferromagnetic transtion, T C1 , of ≈150 K coming from Fe 4+ ‐Fe 4+ interaction explained by electron transfer/leakage from Fe 3+ to Mn 3+ .
