Small quantities (0.1, 0.5 and 1.0 weight percent) of rare earth oxides (La2O3, CeO2, Sm2O3, Gd2O3) and Y2O3 were added to a square-loop Mg-Mn ferrite which contained some ZnO and CuO. The effect of these additions on the static hysteresis loop and the signal to noise ratio was investigated. The samples were prepared by the usual oxide method, sintered 2 hours in air at 1300℃ and quenched from l050℃ or 950℃. Preli-

In order to understand the mechanism of the ionic conduetivity enhancement in LiCl (or LiI) containing dispersed second-phase particles (DSPP), we have performed 7Li NMR investigations on both line width and spin-lattice relaxation time (T1) at 35 MHz in temperature range of 173-483 K. An additional peak was observed to overlap the resonance absorption line. The signal-to-noise ratio was obviously increased while T1 decreased. The profile of this peak changes with type and content of DSPP and temperature....

In order to understand the mechanism of the ionic conduetivity enhancement in LiCl (or LiI) containing dispersed second-phase particles (DSPP), we have performed 7Li NMR investigations on both line width and spin-lattice relaxation time (T1) at 35 MHz in temperature range of 173-483 K. An additional peak was observed to overlap the resonance absorption line. The signal-to-noise ratio was obviously increased while T1 decreased. The profile of this peak changes with type and content of DSPP and temperature. It is concluded that the ionic eonductivity enhancement and the appearing of the additional peak are both given rise by the DSPP of submicron size. The high conduction in the space charge region near the interface between LiCl and DSPP is suggested as a possible mechanism for the ionic conductivity enhancement and the appearing of the additional peak.

本文报道了含分散第二相粒子的离子导体LiCl(或LiI)中~7Li核磁共振的观测结果,测量了~7Li核磁共振吸收谱线的线宽和自旋-晶格弛豫时间(T_1)。实验发现,在LiCl(Al_2O_3)中,~7Li的核磁共振吸收谱线上叠加了一小峰,且随第二相粒子的类型、含量和温度而变化。~7Li核磁共振信号的信噪比显著提高,自旋-晶格弛豫时间变短,且也随第二相粒子的类型、含量和温度而变化。结果表明,离子电导率的提高和附加小峰的出现都是由第二相粒子引起的,从而提出:靠近第二相粒子的LiCl界面附近的空间电荷区中高的离子传导是离子电导率提高和附加小峰出现的可能机理。
