Abstract

Enhanced magnetic transition temperatures are demonstrated in 50 nm thick (001)‐oriented (BiFeO₃)_m/(BiMnO₃)_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 Fe⁴⁺‐Fe⁴⁺ interaction explained by electron transfer/leakage from Fe³⁺ to Mn³⁺.
