Title

Anisotropy of magnetic excitations in pure and electron doped BaFe2As2

Abstract

Previous experiments have shown that pure antiferromagnetic and optimally Co-doped BaFe2As2 exhibit astonishingly similar anisotropy effects, in particular the out-of-plane spin gaps are below the in-plane ones in both cases. We want to extend the studies on pure and Co-doped BaFe2As2 in order to search for longitudinal excitations near the magnetic transition and in order to search for additional anisotropy in the superconducting state.
