Room‐temperature multiferroism in LuFeO 3 (LFO) films is demonstrated by exploiting the orthorhombic–hexagonal ( o–h ) morphotrophic phase coexistence. The LFO film further reveals a magnetoelectric coupling effect that is not shown in single‐phase ( h ‐ or o ‐) LFO. The observed multiferroism is attributed to the combination of sufficient polarization from h ‐LFO and net magnetization from o ‐LFO.
