Magnetic- and electric-field effects on the width, surface tension, and velocity of the interphase boundary are calculated for solid-solid and nematic-isotropic first-order phase transitions described by the Landau expansion with a cubic term. The exact solution of the Ginzburg-Landau-de Gennes equation including an external field is obtained. The results are compared with the experimental data in nematic liquid crystals and ferroelectrics.
