Описание The modern quantum theory of magnetism in solids is getting commonly derived using Green's function formalism. The popularity draws itself from remarkable opportunities to capture the microscopic landscape of exchange interactions, starting from a tight-binding representation of the electronic structure. Indeed, the conventional method of infinitesimal spin rotations, considered in terms of local force theorem, opens vast prospects of investigations regarding the magnetic environment, as well as pairwise atomic couplings. However, this theoretical concept practically is not devoid of intrinsic inconsistencies. In particular, naturally expected correspondence between single and pairwise infinitesimal spin rotations is being numerically revealed to diverge. In this work, we elaborate on this question on the model example and canonical case of body-centered-cubic (bcc) iron bulk crystal. Our analytical derivations discovered the principal preference of onsite magnetic precursors if the compositions of individual atomic interactions are in focus. The problem of extremely slow or even absent spatial convergence while considering metallic compounds was solved by developed technique, based on reciprocal space framework. Using fundamental Fourier-transform-inspired interconnection between this technique and traditional spatial representation, we shed light on symmetry breaking in bcc Fe on the level of orbitally decomposed total exchange surrounding. © 2022 American Physical Society.
