文摘

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.
