In-plane magnetic field effect on the neutron spin resonance in optimally doped FeSe${}_{0.4}$Te${}_{0.6}$ and BaFe${}_{1.9}$Ni${}_{0.1}$As${}_2$ superconductors

We use inelastic neutron scattering to study the effect of an in-plane magnetic field on the magnetic resonance in optimally doped superconductors FeSe${}_{0.4}$Te${}_{0.6}$ ($T_c=14$…
