Low temperature Terahertz Spectroscopy of LaFeO${}_3$, PrFeO${}_3$, ErFeO${}_3$, and LuFeO${}_3$: Quasimagnon resonances and ground multiplet transitions

Nestor E. Massa, Leire del Campo, Vinh Ta Puoc +2

We report on zone center THz excitations of non-Jahn Teller LaFeO${}_3$, PrFeO${}_3$, ErFeO${}_3$, and LuFeO${}_3$ distorted perovskites under external magnetic fields up 7 T. Low temperat…
