Abstract
The characteristic d-type angular dependence of the in-plane magnetoresistance on the orientation of the external magnetic field in the (ab) plane for the antiferromagnetic tetragonal crystal YBa2Cu3O6+x (x ∼ 0.3) is considered theoretically. This dependence is interpreted in terms of the efficient hole transfer through the low-lying purely oxygen O 2pe u doublet, which is not hybridized with the \(b_{1g} (d_{{}_x2_ - {}_y2} )\) ground state. The external magnetic field determines the orientation of the strong exchange field acting on the b 1g e u : 3 E u triplet state of the hole-type CuO4 center. The spin-orbit interaction results in orbital polarization of the E u doublet, which is responsible for the d-type spatial anisotropy of the hole transport. The available experimental data make it possible to evaluate the parameter of the effective spin Hamiltonian. The influence of spin-vibronic effects on the hole transfer is analyzed.
