Description:
<jats:p>Shock-induced demagnetization produced by strain-induced anisotropy is considered in cubic single-crystal ferromagnetic material. Equilibrium thermodynamics, along with established methods of ferromagnetic domain theory, are used to predict energy expressions, magnetization curves, and domain structure in the magnetic material behind the shock wave. In particular, specific expressions for the exchange energy and magnetic self-energy are obtained. They are predicted to increase as the fourth root of the strain and are small compared to the induced anisotropy energy in the region of large elastic and plastic strain. Calculations are made for yttrium iron garnet.</jats:p>
