Hamiltonian field theory of ferrohydrodynamics.
A Hamiltonian field theory of ferrohydrodynamics is derived, with dissipation included by use of a Rayleigh dissipation function. It is shown that kinematic assumptions on the behavior of magnetization under displacements of a volume element of fluid leave a certain freedom in the construction of dynamical equations describing the time-dependence of mass density, flow velocity, entropy density, magnetization, and spin density. The convective behavior of magnetization may be characterized by two dimensionless coefficients.
