From chessboard of bipolarons of size 4a in cubic [Formula: see text] to stripes of the same bipolarons in layered high [Formula: see text] cuprates.

ABSTRACT: The compound [Formula: see text] exhibits a charge order (CO) state at [Formula: see text] and [Formula: see text], which recalls the CO state with a decrease in the temperature of the superconducting transition, [Formula: see text], observed in all cuprates at this doping value. Local excitations of lattice and magnetic origins measured in the two-dimensional metallic state of [Formula: see text] reveal the existence of bipolarons of size 4a resulting from structural and antiferromagnetic pairings of hole-rich orbital polarons of size 2a. They are intertwined with hole-poor domains in a disordered state at [Formula: see text] which become ordered on a chessboard organized in a 3D-order state of ferromagnetically paired polarons at [Formula: see text]. Applied to the [Formula: see text] pl
