We determine the form of axisymmetric toroidal magnetic fields in neutron stars, where protons form a type II superconductor, consistent with the requirements of hydrostatic balance. We calculate the quadrupolar distortions due to such fields, and find that the star can be sufficiently distorted to display precession with a period of the order of years, as is observed in PSR B1828-11. We study the stability of these fields using an energy principle, and extend the stability criteria established by R. J. Tayler for normal conductors to more general media with magnetic free energy that depends on density and magnetic induction, such as type II superconductors. We also derive the timescale for a specific instability of type II superconductors, first discussed by P. Muzikar, C. J. Pethick and P. H. Roberts.
