abstract = {We use inelastic neutron scattering to study the effect of
a magnetic field on the neutron spin resonance(Er=3.6 meV)
of superconducting FeSe (Tc=9 K). While a field aligned
along the in-plane direction broadensand suppresses the
resonance, ac-axis aligned field does so much more
efficiently, consistent with the anisotropicfield-induced
suppression of the superfluid density from the heat capacity
measurements. These results suggestthat the resonance in
FeSe is associated with the superconducting electrons
arising from orbital selectivequasiparticle excitations
between the hole and electron Fermi surfaces.},
