Galois groups distinguish the part of 3d electrons in a volume of ‘orbital glass’ (OG). That renormalizes spectrum ~εk of band fermions. Increasing of their mass Δεk(Lp)≅ 0.1 eV increases effective mass of d fermions by Δm∗≈(1−10)m∗ for part of 3d band in the OG volume. The value of orbital moment decreases (L < 1) that explains measured orbital moments of 3d ions (Co, Ni, etc.).
Ключевые слова: Galois groups, ‘orbital glass’, heavy electrons, orbital moments of 3d ions.
