Implementing Room-Temperature Multiferroism by Exploiting Hexagonal-Orthorhombic Morphotropic Phase Coexistence in LuFeO3 Thin Films

Room‐temperature multiferroism in LuFeO3 (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 attribut...

Zusammenfassung:	Room‐temperature multiferroism in LuFeO3 (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.
