Electron-magnon interaction effect in antiferromagnetic superconductors. Proposal of a tunneling experiment

  • Published:
Journal of Low Temperature Physics Aims and scope Submit manuscript

It is shown that in an antiferromagnetic superconductor the electronic density of states is modified to exhibit a deviation from the BCS theory due to the second-order process of the electron-magnon interaction. An electron tunneling experiment is proposed to detect this effect in existing antiferromagnetic superconductors. A close analogy is pointed out between the present electron-magnon system and the electron-phonon system of strong coupling superconductors.
