Intrinsic magnetic polarizability contribution to susceptibility of dense neutron matter

1975

It is shown that, apart from the neutron interaction contribution to the susceptibility of neutron stars, there is an additional contribution coming from the magnetic polarizability beta /sub n/ of individual neutrons. For beta /sub n/ approximately=10/sup -4/fm/sup 3 /, this part overwhelms the interaction contribution for k/sub F/>or approximately=3.5fm/sup -1/. No transition to ferromagnetic state is predicted in the interesting density region.
