Abstract
Infrared transmission, magnetic birefringence, and Faraday rotation have been measured in single crystals of EuO as a function of temperature and magnetic field in the wavelength region between 1.5 and 20 μ. The most transparent samples have an absorption coefficient at 20°K less than 0.5 cm−1 in the range between 2.5 and 9 μ and less than 1.0 cm−1 at 10.6 μ. At 20°K and 9 kG the Faraday rotation varies from 660 deg/cm at 10.6 μ to 3 × 104 deg/cm at 2.5 μ and over 105 deg/cm at 1.5 μ.Keywords
