Abstract
The electron paramagnetic resonance spectra of Cr3+ in LiNbO3 co-doped with ZnO or CaO (approximate to 6%) have been studied. Both impuritie s give rise to the same effect as that observed in MgO-doped samples: a strong diminution of the anisotropic (axial) spectrum reported for L iNbO3:Cr and the appearance of an intense and isotropic line. The orig in of this line in the co-doped samples is discussed.
