Spin-space anisotropy and longitudinal mode in Co underdoped BaFe2As2
We propose to study the spin-space anisotropy of magnetic excitations in weakly doped (3%Co) BaFe2As2 in order to search for the longitudinal magnetic excitations. This material should be best suited for this purpose as the energy scales are favorable compared to a pure compound and as the reduced ordered moment suggests stronger longitudinal excitations. In addition the obtained information will be most relevant for the understanding of the superconducting phase appearing at slightly larger doping.
