The observation of dislocations in yttrium gallium garnet by a photoelastic method

  • M. J. Prescott
  • J. Basterfield


A brief outline of the technique for observing dislocations by their photoelastic patterns is given. The method is successfully applied to the determination of Burgers vectors of dislocations in flux-grown single crystals of yttrium gallium garnet, and the origin and elimination of dislocations in this material is discussed.
