Abstract

Inelastic neutron scattering measurements on Ba(Fe_0.963Ni _0.037)₂As₂ manifest a neutron spin resonance in the superconducting state with anisotropic dispersion within the Fe layer. Whereas the resonance is sharply peaked at the antiferromagnetic (AFM) wave vector Q_AFM along the orthorhombic a axis, the resonance disperses upwards away from Q_AFM along the b axis. In contrast to the downward dispersing resonance and hourglass shape of the spin excitations in superconducting cuprates, the resonance in electron-doped BaFe ₂As₂ compounds possesses a magnonlike upwards dispersion.
