Abstract

We present theoretical evidence that a magnetic monopole emerges in dynamic magnetic systems in the presence of the spin-orbit interaction. The monopole field is expressed in terms of spin damping associated with magnetization dynamics. We demonstrate that the observation of this spin damping monopole is accomplished electrically using Ampere's law for monopole current. Our discovery suggests the integration of monopoles into electronics, namely, monopolotronics.
