Electronic and Structural Properties of Oxides

Resumo

Mixed-valent manganese oxides with perovskite structure offer a certain degree of chemical flexibility that allows making systematic studies of the relationship between the electric and magnetic properties with the crystalline structure.Here we present magnetic measurements in La 2/3 (Ca 1-x Sr x ) 1/3 MnO 3 that demonstrate that the adiabatic approximation breaks down at low x, due to the strong coupling of the electronic and the lattice degrees of freedom.
