Far Infrared Absorption by Small Bismuth Particles

Abstract

We have observed low frequency (<50 cm-1) magnetic field dependent resonances and higher frequency resonances at zero field in the far infrared (FIR) absorption of small bismuth particles. A model based on the quasistatic approximation shows both good agreement with previous measurements of resonance frequencies vs. field and qualitative agreement with our data.
