Hopping nature of the Hall effect in a samarium nickelate film
We analyzed the temperature dependencies of the DC resistivity and Hall coefficient in thin films of samarium nickelate SmNiO3. A dominating hopping […]
Small-polaron conductivity in perovskite ferroelectric BaTiO₃ films
In ABO₃ perovskite oxide ferroelectrics, electrical conductivity ranges from insulator- to superconductor-type and is virtually critical for all applications of these materials. […]
