Direct measurement of polaron binding energy in AMnO${}_3$ as a function of the A site ionic size by photoinduced IR absorption

T. Mertelj, M. Hrovat, D. Kuščer +1

Photoinduced IR absorption was measured in undoped (LaMn)_{1-δ}O_{3} and (NdMn)_{1-δ}O_{3}. We observe broadening and a ~44% increase of the midinfrared anti-Jahn-Teller polaron pe…
