3D correlations in high Tc copper oxides
Abstract
Large spin orbit interaction between the localized spins and itinerant holes is able to establish the magnetic order that preserves the T-invariance but breaks the parity. In a highly anisotropic high Tc cuprates, this ordering involves the spins on adjacent planes. If the spins on each plane form a spin liquid state, this transition can be described as a the spinon paring on adjacent planes. This scenario may explain the optical activity of the high Tc materials, their anomalous resistivity perpendicular to the planes, orbital magnetic susceptibility, the quasigap behaviour of spin correlators in NMR and provides the mechanism for the superconductivity.
