Abstract : Single crystals of several perovskite materials including CsMnF3, alkali chloride-manganese chloride salts and Er3Fe5O12 have been prepared. The Faraday rotation of crystals of Er3Fe5O12 have been measured at 1.15 micrometers at room temperature and at liquid nitrogen temperature (i.e., below the compensation point). The use of this material as an optical memory is discussed. The optical properties of single crystals of several chloride salt of manganese have been measured. The results obtained for the fluorescence are compared with measurements on several fluoride salts. (Author)
