Description:
Author(s): R. Nourafkan and S. Acheche The unconventional temperature variation of the Knight shift (static spin susceptibility) that has been observed in Fe-based superconductors A Fe 2 As 2 ( A = K , Rb, Cs) is explained in terms of proximity to a van Hove singularity. Using the Hubbard model we show that when the Fermi energy is in the vicini... [Phys. Rev. B 98, 161116(R)] Published Wed Oct 17, 2018
