| Abstract: | Quoting the average covalent factor and adopting the Point-Charge Model,this paper studies the absorption spectra and g-factor for SrAl12O19 :Mn2+crystal,and the calculated results demonstrate they are in good agreement with the experimental results.Additionally,exploiting the value of g-factor at 110K,we obtain the relationship between bond length and temperature variation. |
