Fabrication and Transport Properties of Manganite-Polyacrylamide-Based Composites

Fabrication and Transport Properties of Manganite-Polyacrylamide-Based Composites

We present the fabrication and transport properties of a series of composites made of La2/3Sr1/3MnO3 and acrylamide-based copolymers. The most important result is the very narrow transition, of only 27 K, displayed by the peak that appears around the metal-insulator transition of the composites made...

The most important result is the very narrow transition, of only 27 K, displayed by the peak that appears around the metal-insulator transition of the composites made with poly(acrylamide-vinylacetate). Although the amount of polymer is rather low, different copolymers change drastically the electric transport characteristics.http://dx.doi.org/10.1155/2009/429430
