Abstract

In crystal and ceramic LiNbO3 double doped with Mg or Zn above the threshold concentration (C-Mg,C-Zn greater than or equal to 4-6 mol%) and with transition metals of the 3d group (Cr, Fe, Mn) non-resonant microwave absorption (NRMA) dependent on the magnetic field was studied. Peak-like dependencies of the NRMA signal intensity on the concentration of dopants and stoichiometry of lithium niobate were found. The EPRline of mobile electrons (Delta B = 30 mT) with g = 2.0023 was detected. The interaction energy between the substitutional impurities of Mgand Cr was calculated. It was concluded, that in LiNbO3 : (Mg, Zn) : (Cr, Fe, Mn) ordered metallic chains exist with electron conductivity. (C) 1998 Elsevier Science B.V. All rights reserved.
