Powder sample electron paramagnetic resonance (EPR) spectrum ofCr3+ions inYAlO3crystals contains off-axis extra lines, which do not belong to the principalX, Y,andZcomponents of the fine structure. Orientation dependence of the EPR spectrum ofCr3+dopedYAlO3single crystal confirms the existence of extra turning points corresponding to directions lying off theX, Y,andZaxes, consistent with theoretical predictions. This results in five EPR lines due to the transition between the central Kramers doublet in the powder system. The observed powder pattern EPR has been used in identification ofCr3+as an impurity ion in undopedYAlO3crystals. ©1997 American Institute of Physics.
