V.Medvedeva2018-11-072018-11-072013https://resolver.sub.uni-goettingen.de/purl?gro-2/30311A new concept is introduced which can develop interface electroresistive (ER-) and pulse electro-resistive (EPIR-) effects far from phase transition temperatures and phase separation regions. It is based on strong self-trapping effects in mixed manganites, but this self-trapping is rather connected with larger defect trap states, not just with trapped electrons or holes. Due to a peculiar electrical field induced feedback, this self-trapping does not occur at random, but rather tends to build up space charge accumulation layers which are not at equilibrium with the matrix free carriers.
