ESR study of color centers in yttria stabilized zirconia

The ESR of single crystals of yttria stabilized zirconia (YSZ), containing color centers due to reduction in a flowing H 2 atmosphere, has been measured at room temperature. The spin density is about 3×10 17 cm −3 and the strong ESR line displays axial symmetry with principal values g⊥ = 1.860. The...

Description
Summary:The ESR of single crystals of yttria stabilized zirconia (YSZ), containing color centers due to reduction in a flowing H 2 atmosphere, has been measured at room temperature. The spin density is about 3×10 17 cm −3 and the strong ESR line displays axial symmetry with principal values g⊥ = 1.860. The behaviour of the ESR spectra when the magnetic field is rotated about the and directions shows that the centers have axial symmetry, the symmetry axis being along the directions. The results are interpretable in terms of an electron trapped at an oxygen vacancy adjacent to an yttrium ion.
