Abstract
A simple scheme to use Néel skyrmions hosted in a ferromagnetic material as information entropy carriers based on the analogy between the Boltzmann’s configurational entropy and the continuous limit of Shannon’s information entropy is outlined. It is proposed a simple application represented by a data communication system able to transmit information entropy. The binary source fixes the skyrmion thermodynamic state, and the ferromagnet in contact with a thermal bath and hosting the magnetic skyrmion is regarded as the communication channel. The magnetic skyrmion enables the transmission of the information entropy from the source to the receiver. Analytical and numerical calculations show that the information coded by the magnetic skyrmion increases as the information content diminishes in accordance with the rules of Shannon’s information systems. These results could pave the way to use magnetic skyrmions as carriers of information basing on their thermodynamics.
