Abstract

Measurements were made of Faraday rotation on ∼1 μ thick evaporated and recrystallized polycrystalline InSb films. The experiments were carried out at room temperature using TE11 circular waveguide with dc magnetic fields up to 7 kOe. Rotations on the order of 50 deg were observed. The experimental results are in reasonable agreement with a theoretical model based on free-carrier Faraday rotation, including multiple reflections, using the mobilities and carrier concentrations found by separate dc measurements.
