Cyrstal field splitting and optical band gap of hexagonal LuFeO${}_3$ films

Wenbin Wang, Hongwei Wang, Xiaoying Xu +8

Hexagonal LuFeO${}_3$ films have been studied using x-ray absorption and optical spectroscopy. The crystal splittings of Fe${}^{3+}$ are extracted as $E_{e^{\prime }}-E_{e"}$=0.7 eV and $E_{a_1…
