Abstract
Colossal magnetoresistance and giant magnetoresistive memory effect have been demonstrated in the electron-doped manganite superlattices composed of alternatively of G-type antiferromagnetic insulator (G-AFI) layers of CaMnO3 and C-type antiferromagnetic insulator (C-AFI) layers of Ca0.92Ce0.08MnO3. The transport properties of the superlattices strongly depend on the periodicity and the unit cells of each layer. The charge transfer through the interface of the constituent insulators induces appearance of the canted G-type antiferromagnetic metal (cG-AFM) phase in the superlattices. Enhanced colossal magnetoresistance and memory effect emerge in the superlattices composed of the thinner G-AFI layers, which can be attributed to the artificially generated two-dimension-like phase competition between cG-AFM and C-AFI in the charge transfer region. The effective charge transfer through interface provides us an opportunity to control phase separation and thus tailoring electronic properties of electron-doped manganites.
