Abstract

Electron magnetic resonance (EMR) of paramagnetic Cr$^{3+}$, Mn$^{2+}$, and Fe$^{3+}$ impurity ions in ferroelectric LiNbO$_3$ and LiTaO$_3$ single crystals has been studied. The actual sites location of paramagnetic impurity ions in the crystals was suggested from the experimental results and zero field splitting parameters calculated by superposition model. It turns out that Cr$^{3+}$ ions in LiNbO$_3$ crystal have two resonance centers and enter both the Li$^{+}$ and Nb$^{5+}$ ions. Mn$^{2+}$ and Fe$^{3+}$ impurity ions in LiNbO$_3$ substitute for Nb$^{5+}$ ions. However, both Cr$^{3+}$ and Fe$^{3+}$ ions in LiTaO$_3$ crystal reside at Li$^{+}$ ions.$ +/ ions.+/ ions.

강유전체 물질인 LiNbO$_3$ 및 LiTaO$_3$ 단결정 내에 불순물로 첨가되어 있는 상자성 전이원소인 Cr$^{3+}$ , $Mn^{2+}$, Fe$^{3+}$ 이온에 관한 전자 자기공명 연구를 하였다. 이들 두 단결정 내에 들어있는 불순물 이온에 대하여 중첩모델을 써서 계산한 영자기장 갈라지기 상수의 값을 실험에서 얻은 영자기장 갈라지기 값 및 기존에 보고된 많은 연구 논문과 비교 분석하여 상자성 불순물이 결정 내의 어느 자리를 치환하고 들어가는지를 연구하였다. LiNbO$_3$ 단결정 내의 Cr$^{3+}$ 이온이 불순물로 들어 갈 경우에는 두 가지 공명 중심이 가능하며, Li$^{+}$ 및 Nb$^{5+}$이온 자리를 각각 치환하고 들어간다. 또한 LiNbO$_3$ 결정 내의 $Mn^{2+}$ 및 Fe$^{3+}$ 이온의 경우에는 두 이온 모두 Nb$^{5+}$ 이온 자리를 치환하고 들어간다. LiTaO$_3$ 단결정 내에 불순물로 들어가 있는 Cr$^{3+}$ 및 Fe$^{3+}$ 이온은 모두 Li$^{+}$ 이온 자리를 치환하고있는 것으로 나타났다.
