Inertial spin alignment in a circular magnetic nanotube

TL;DR

This paper predicts a novel spin alignment phenomenon in circular magnetic nanotubes where electron orbital motion influences spin dynamics, significantly altering ferromagnetic behavior.

Contribution

It introduces the concept of inertial spin alignment caused by electron orbital motion in magnetic nanotubes, a novel effect not previously described.

Findings

Magnetic energy of the spin is strongly reduced.

New spin precession axis nearly parallel to nanotube axis.

Ferromagnetic physics is significantly modified.

Abstract

In Co-nanotubes with a curling magnetization, the orbital motion of the conduction electrons interacts with their spin. We predict that the (absolute) value of the magnetic energy of the spin is strongly reduced. The new precession axis for the spin is almost parallel to the axis of the nanotube and precesses with the angular velocity of the electron. The physics of the ferromagnet is considerably modified.
