1953 - 1954
Magnetic analogue of critical opalescence
Shoot a beam of neutrons at a magnetic material, and part
of the observed scattering will be due to the interactions
of the atomic magnetic moments with the moment of the
neutron. Near the critical temperature region the
scattering cross section increases sharply, the magnetic
analogue of critical opalescence. Palevsky & Hughes and
Squires first observe the effect in iron.
