Description
ESR method was used to investigate defect formation in LMNO crystals (LiNbO3, alloyed with magnesium) under the effect of thermal annealing, to study the influence of 3d-ion (Ni, Ti, Cr, Fe) additions on radiation defect formation under γ-irradiation (at T = 77 K) of such crystals, and to study Mn2+ and Ni+ESR in LMNO. Further investigations of nonresonance magneto-depending microwave absorption (MA) near the zero magnetic field in LMBO:Mn crystals, as well as in LZNO:Cr crystals and ceramics (LiNbO3:Zn(10 mol%):Cr) were conducted. A new MA signal in the form of magnetization loop in magnetics was revealed in LMNO:Mn crystals and LZNO:Cr ceramics. It was also revealed, that MA in LMNO and LZNO was characterized by temperature hysteresis. 18 refs., 5 figs., 3 tabs
