Title: Chiral surface and edge plasmons in ferromagnetic conductors

Abstract

The recently introduced concept of "surface Berry plasmons" is studied in the concrete instance of a ferromagnetic conductor in which the Berry curvature, generated by spin-orbit (SO) interaction, has opposite signs for carrier with spins parallel or antiparallel to the magnetization. By using collisionless hydrodynamic equations with appropriate boundary conditions, we study both the surface plasmons of a three-dimensional ferromagnetic conductor and the edge plasmons of a two-dimensional one. The anomalous velocity and the broken inversion symmetry at the surface or the edge of the conductor create a "handedness" whereby the plasmon frequency depends not only on the angle between the wave vector and the magnetization, but also on the direction of propagation along a given line. In particular, we find that the frequency of the edge plasmon depends on the direction of propagation along the edge. These Berry curvature effects are compared and contrasted with similar effects on plasmon dispersions induced by an external magnetic field in the absence of Berry curvature. Here, we argue that Berry curvature effects may be used to control the direction of propagation of the surface plasmons via coupling with the magnetization of ferromagnetic conductors, and thus create a link between plasmonics and spintronics.

FIG. 1 FIG. 1: Variation of the 3D ferromagnetic surface plasmon frequency $ω$+ (scaled by $ω$$S$) with the in-plane wave vector q. The set-up of the system is shown schematically in panel (a) with $\phi$$q$ defined as the angle between the direction of propagation of the surface plasmon and the direction ofmore » magnetization fixed on the $x$-axis. Panel (b) shows $ω$+ as a function of $\phi$$q$ at a fixed magnitude of the wave vector of $q$ = 0.1$k$$F$ for several different values of $τ$$so$ (scaled by $ω^{−1}_{B}$ ), panel (c) shows $ω$+ as a function of the magnitude of the wave vector $q$ for several different angles $\phi$$q$ with a given SO interaction strength $ω$$B$$τ$$so$ = 0.5, and panel (d) is a schematic picture showing the range of $\phi$$q$ (plasmon propagation directions) for which the surface mode is forbidden when the quantity |$\mathcal{P}ω$$S$$τ$$so$| is greater than $\frac{1}{\sqrt{2}}$ . Note that the Fermi wave vector $k$$F$is related with the 3D equilibrium electron density via $n$0 = $\frac{k^{3}_{F}}{3π^2}$ .« less
