摘要：

All energy-band calculations of Gd show seven very-narrow minority-spin 4f bands just above the Fermi energy. We show that this resonance is an artifact of the local-spin-density approximation and suggest that it is the reason that all calculations have yielded electronic densities of states at the Fermi energy larger than the experimental value.
