Abstract
We analyze a simple model containing the physical ingredients of a Hund's metal, the local spin fluctuations with power-law correlators, (Ω0/|Ω|)γ, with γ greater than one, interacting with electronic quasiparticles. While the critical temperature and the gap change significantly with varying parameters, the 2Δmax/kBTc remains close to twice the BCS value in agreement with experimental observations in the iron-based superconductors (FeSC).
