The magnetic neutron scattering resonance of high-T_c superconductors in external magnetic fields: an SO(5) study

Niels Asger Mortensen, H. M. Ronnow, Henrik Bruus +1

The magnetic resonance at 41 meV observed in neutron scattering studies of Y Ba_2 Cu_3 O_7 holds a key position in the understanding of high-T_c superconductivity. Within the SO(5)…
