Nonquasiparticle states in half-metallic ferromagnet NiMnSb
arXiv:cond-mat/0310032 · doi:10.1103/PhysRevB.68.144425
Abstract
Nonquasiparticle states above the Fermi energy are studied by first-principle dynamical mean field calculations for a prototype half-metallic ferromagnet, NiMnSb. We present a quantitative evaluation of the spectral weight of this characteristic feature and discuss the possible experimental investigation (BIS, NMR, STM and Andreev reflection) to clarify the existence of these states.
