“…The MgAl 2 O 4 is one of such material which has considerable radiation resistance (Yoshimura et al, 2006), chemical inertness, high melting point and good mechanical strength. These properties have made to realize the utility of MgAl 2 O 4 as an optical and insulating material in the radiation field (Sheehan et al, 1993;Baudim wet al, 1995;Tripathi et al, 2003;Paris et al, 2009;Deepak et al, 2007;Kinoshita et al, 1995). In MgAl 2 O 4, cation antisite defects were produced by Al 3+ and Mg 2+ inversion (Gritsyna et al, 2006 ).…”
