Magneto-elastic Waves in Metals

摘要

Magneto-elastic waves in electron plasma of crystalline metals are investigated using a nonlinear selfconsistent theory based on the nonlinear theory of elasticity, Boltzmann-type transport equation and Maxwell's equations. Electrons are considered as quasiparticles with arbitrary dispersion relations which depend on the local lattice deformations. The electron-lattice interaction results from this variation of the dispersion law. The inertial forces due to the noninertial motion of the crystal lattice during the time varying deformations are taken into account as well. It is shown that an effective magnetic field exists which vector lines are pinned to the lattice and its effect on the lattice vibrations is obtained and discussed.
