ELECTRON-PARAMAGNETIC-RESONANCE OF MN2-STABILIZED CUBIC ZIRCONIA SINGLE-CRYSTAL( IN YTTRIA)

Yttria stabilized cubic zirconia single crystal doped with the Mn2+ io n was grown by the Bridgman-Stockbager method using a cold container. The electron paramagnetic resonance of Mn2+ ion in cubic single crysta l [(ZrO2)(0.77)(Y2O3)(0.23): Mn2+] has been investigated in the temper ature range 110 similar to 500 K TWO Mn2+ centers are originated from the Mn2+ ions reside at Zr4+ and Y3+ ion sites from the analysis of th ree resolved hyperfine structures. The Mn2+ ions at Zr4+ and Y3+ sites are remotely compensated without nearby charge compensation. It turns out that Mn2+ ions reside at cubic symmetry sites from the rotation p attern of Mn2+ ions.
