Abstract

The electrical and optical properties of single crystals of Ni, Ni + Zr, and Fe doped Y3Al5O12(YAG) were studied as a function of temperature, atmosphere and composition. The often dramatic changes in properties observed for these materials are interpreted in terms of the underlying defect structure of these materials. Defect formation and migration energies are derived as well as the position of energy states within the gap.
