Polaronic transport induced by competing interfacial magnetic order in a La${}_{0.7}$Ca${}_{0.3}$MnO${}_3$/BiFeO${}_3$ heterostructure

Using ultrafast optical spectroscopy, we show that polaronic behavior associated with interfacial antiferromagnetic order is likely the origin of tunable magnetotransport upon swit…
