Abstract
This paper investigates the behavior of the Verdet constant for cobalt ferrite (CoFe<inf>2</inf>O<inf>4</inf>) nanoparticles polymer composite films at low temperatures using a 532 nm laser source. An experimental setup for Faraday rotation (FR) at low temperatures is introduced and FRs were measured at various temperatures. Verdet constants were deduced from the paramagnetic model for terbium gallium garnet glass where ∼4× improvement was observed at 40°K for CoFe<inf>2</inf>O<inf>4</inf>composite film.
