Material forces in thermoelastic ferromagnets

A systematic construction of the canonical balance of momentum (“pseudomomentum” on the material manifold) and energy is presented for materially inhomogeneous thermoelastic hard ferromagnets in which both exchange forces and magnetic-spin inertia are taken into account. The latter is of the gyroscopic type and endows the sources of quasi-inhomogeneities in the balance of pseudomomentum with special properties. The equations obtained will prove useful in further studies of the fracture of hard ferromagnets and of the propagation of phase-transition fronts in such materials. Received January 23, 1996
