Abstract

We present the results of a theoretical and experimental investigation of long-range surface magnetoplasmons in thin, magnetic metal films. With a transversely applied magnetic field, the reflectance modulation measurements from prism-coupled modes in nickel films are in agreement with the theory. The reflectance modulation is the same order of magnitude for prism-coupled long-range and single-interface magnetoplasmons.

The bounding refractive indices are 1.5.

Experimental (solid curves) and theoretical (dashed curves) reflectance, R, and differential reflectance, ΔR, for the prism-coupled LRSMP of a 24.5-nm nickel film at a wavelength of 632.8 nm. Theoretical ΔR is for a 1.2-nm inert layer (short-dashed curve) and no inert layer (long-dashed curve) at the top nickel surface.
