2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/29077We revisit the transport properties of La-Ca manganites in detail, since they have been confirmed in a number of CMR-exhibiting materials. We also discuss new data considered the hallmark of an unusually high electron-phonon coupling responsible for charge localization and small polaron transport.23 pages, 7 comb. figures, 98 references.
