Off-axis extra lines in powder pattern electron paramagnetic resonance of Cr{sup 3+} in YAlO{sub 3}
- Center for Materials Research, Norfolk State University, Norfolk, Virginia 23504 (United States)
Powder sample electron paramagnetic resonance (EPR) spectrum of Cr{sup 3+} ions in YAlO{sub 3} crystals contains off-axis extra lines, which do not belong to the principal X,Y,and Z components of the fine structure. Orientation dependence of the EPR spectrum of Cr{sup 3+} doped YAlO{sub 3} single crystal confirms the existence of extra turning points corresponding to directions lying off the X,Y, and Z axes, 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 of Cr{sup 3+} as an impurity ion in undoped YAlO{sub 3} crystals. {copyright} {ital 1997 American Institute of Physics.}
