摘要: 本文报道Agl(Cr2O3)混合离子导体的电子自旋共振(ESR)实验结果。观测到一种新的稳定的ESR信号,它可能对应于Agl和Cr2O3界面层内与Ⅰ-空位相关(类似F心)的缺陷,这种缺陷的存在可能是提高Ag+电导率的重要因素。

Abstract: This paper reports the results of the Electron Spin Resonance (ESR) experiment of the mixed ionic conductor Agl (Cr2O3). A kind of new stable ESR signal was observed, which might be assigned to certain defects (similar to F center) in the boundary layer between components Agl and Cr2O3.The existence of the defects may be an important factor for improving Ag+ ionic conductivity.
