Synthesis, Structure, and Properties of the Layered Perovskite La 3 Ni 2 O 7-δSingle-phase samples of La 3 Ni 2 O 7-δ with δ = 0, 0.08, and 0.65 were prepared and characterized by powder X-ray diffraction, TGA, electrical resistivity, and magnetic susceptibility. The crystal symmetry...
The electrical properties of the homologous series La n+1Ni nO 3n+1, with n=2, 3 are discussed and compared in terms of the dimensionality of the crystal lattice and the electronic band structure calculated by the extended Hueckel tight binding method...
a Schematic pristine crystal structure of La3Ni2O7. b Top view of the crystal structure with a two-dimensional lattice of O and Ni atoms. Due to the out-of-plane tilted Ni-O octahedra, the apical oxygen atom is not right on the top of Ni atom. The solid black line frame represents...
