The temperature dependences of a Verdet constant of ceramic samples with the compositions (DyxY0.95-xLa0.05)(2)O-3, x = 0.7, 0.85, 0.9 and their approximations in the temperature range 80-294 K and in the wavelength range 405-1064 nm were obtained with the <10% deviation from the experimental data. Cryogenic cooling leads to increase the Verdet constant value, proportional to inverse temperature, which allows to shorten a magneto optical element length in cryogenic Faraday isolators. Results obtained are necessary for developing of Faraday devices for Tm3+ and Ho3+ lasers, and for lasers operating in the visible spectral region. (C) 2018 Acta Materialia Inc.
