Abstract
We report small angle (SANS) and inelastic neutron scattering in zero and applied field for a-FeMn, NiMn and AuFe at composition where both ferromagnetic and frustration characters occur. We discuss the field evolution of the transverse correlations which arise below Tc. A study of the field dependence of the spin wave anomalies in a-Fe-Mn is reported.
