摘要：

We have used the pseudofunction method to compute self-consistent spin-polarized energy bands for La2CuO4. The ground state is found to be semiconducting and antiferromagnetic (AF) with a moment of 0.35B. The net moment resulting from the occupation of 82 itinerant bands is localized on the Cu atoms only. Our results agree with experiments in which La2CuO4 is found to be semiconducting and AF with a moment on the Cu atoms of (0.35±0.05)B (neutron scattering) or in the range 0.2B to 0.6B (muon-spin resonance). Sr is found to produce holes on the out of plane O contrary to the assumption used in many strong-correlation theories of superconductivity. © 1990 The American Physical Society.
