The insulator state of ultrathin films of ferromagnetic manganites
Source abstract
Abstract
Abstract We have investigated transport, magnetization and structure of La 0.7 Ca 0.3 MnO 3 (LCMO) and La 0.7 Sr 0.3 MnO 3 (LSMO) ultrathin films with thicknesses down to 1.6 nm. The insulator state appears below 3.5 and 2.3 nm for LCMO and LSMO, respectively. It originates from interface behavior and reduced dimensionality rather than from effects of epitaxial strain. Insulating LSMO films show bias-induced conductance.
