Theory of antiferromagnetic resonance

Antiferromagnetic structures were first shown through neutron diffraction of transition metal oxides such as nickel, iron, and manganese oxides. The experiments, performed by Clifford Shull, gave the first results showing that magnetic dipoles could be oriented in an antiferromagnetic structure. Antiferromagnetic materials occur commonly among transition metal compounds, especially oxi… WebbIn the last section we consider antiferromagnetic resonance.
