EMR study and superposition model analysis of Cr3+ and Fe3+ impurity ions in mullite powders used in aerospace industry

“…Standardization of orthorhombic and monoclinic ZFS (as well as crystal fi eld) parameters [23,24] will be considered in a full paper. Preliminary results for the impurity Cr 3+ and Fig.…”

EPR and optical study of Mn2+ doped monohydrated dipotassium stannic chloride

“…The above approximations may have a little affect on the fitted value of a [12,13]. The direction of the maximum overall splitting of EPR spectra is taken as the z axis and the minimum as the x axis [14]. The laboratory axes (x, y, z) are parallel to the crystallographic axes (CA) (a, b, c).…”
