Charged-particle induced local polarization and local magnetization of a metal

Abstract
Aim: We show that when a single elementary charge passes through a metal, local polarization and magnetization occur in its volume along its entire trajectory.
Methodology. The research method is based on solving the equations of motion for a charged particle.
Results. It is proved that when a fast-flying charged particle passes through a metal, short-lived spin waves (magnons) and polarization waves appear in it, which disappear after the “transit” time τ = L/v , where L is the thickness of the metal and the v is the electron velocity.
Research implications. A physical justification and an analytical description of the motion of a fast-flying charged particle through a metal are proposed. The phenomenon of polarization and possible existence of short-lived spin waves are predicted.
