Enhanced Multiferroicity in LuFeO$_{3}$ Through Sc Doping*

Hexagonal manganites of the type \textit{R}MnO$_{3}$ are well known examples of single-phase multiferroic materials, but suffer from low magnetic ordering temperatures and weak magnetoelectric coupling making them unsuitable for implementation in devices. Recently, the isostructural ferrites \textit{R}FeO$_{3}$ have been proposed as promising materials to exhibit greatly enhanced magnetic properties, including a much stronger coupling mechanism between ferromagnetic moment and ferroelectic polarization. Here we present a magnetometry and neutron scattering investigation of LuFeO$_{3}$ forced into the ferroelectric structure through Sc-doping. We find the magnetic ordering temperature dramatically increases relative to pure hexagonal LuFeO$_{3}$ and LuMnO$_{3}$, as well as an unusual spin-reorientation at low temperatures. We will discuss possible mechanisms for this reorientation and how it provides insight into the enhanced magnetic properties Limit of the \textit{R}FeO$_{3}$ series.
