Mechanism of Basal-Plane Antiferromagnetism in the Spin-Orbit Driven Iridate Ba_{2}IrO_{4}
By ab initio many-body quantum chemistry calculations, we determine the strength of the symmetric anisotropy in the 5d^{5} j≈1/2 layered material Ba_{2}IrO_{4}. While the calculated anisotropic couplings come out in the range of a few meV, orders of magnitude stronger than in analogous 3d transition...
