Ferromagnetism in nuclear matter and its implication for the
neutron star equation of state
Jacobus Diener
Stellenbosch University
Under the extreme conditions in the neutron star interior the proton and
neutron magnetic dipole moments could increase well beyond their values
observed under normal conditions. If such an increase in the dipole
moment is sufficient, the matter in the interior of the star can undergo
a ferromagnetic phase transition. The generated magnetic field should be
of the order of the observed magnetar magnetic field and can thus make
a considerable contribution to the star~Rs magnetic field. This talk
reports on the conditions of such a phase transition in charge neutral,
beta-equilibrated nuclear matter and its implication for the neutron star
equation of state. Possible observational consequences of such a phase
transition will also be discussed.
