Lattice source for charge and spin inhomogeneity in 2D perovskite cuprates

Vladimir A. Gavrichkov, Semyon I. Polukeev

In the work we highlight the structural features of 2D perovskite cuprates (tilted CuO $_{6}$ octahedra with different orientation with respect to spacer rocksalt layers), where sourc…

Magnetic Interaction in Doped 2D Perovskite Cuprates with Nanoscale Inhomogeneity: Lattice Nonlocal Effects vs Superexchange

V. A. Gavrichkov, S. I. Polukeev

We have studied the superexchange interaction $J_{ij}$ in doped $2 D$ cuprates. The AFM interaction strongly depends on the state of the lattice of a CuO $_{2}$ layer surrounded by two…
