| Abstract: | There should be two contributions to the pair breaking energy in an antiferromagnetic metal. The first, already discussed byde Gennes andSarma, is due to disorder on the magnetic sites. The second is a temperature dependent contribution from electron magnon scattering. This term is calculated for the temperature rangeT N(J/μ)2?T?T N and found to be of orderT 2/T N. (T N = Néel temperature,μ = Fermi energy,J = exchange coupling between conduction electrons and magnetic ions.) |
