Neutron analysis reveals 'two doors down' superconductivity link

Neutron analysis reveals 'two doors down' superconductivity link
Neutron scattering analysis of two families of iron-based materials suggests that the magnetic interactions thought responsible for high-temperature superconductivity may lie "two doors down": The key magnetic exchange pairings occur in a next-nearest-neighbor ordering of atoms, rather than adjacent atoms.
