A MSSBAUER STUDY FOR ANOMALOUS PROPERTIES OF LiNbO_3 CRYSTAL NEAR 75℃
收藏 引用
Chinese Science Bulletin 1983年 第5期28卷 604-608页
作者: 夏元复 许自然 沈惠敏 刘荣川 甘肇强 王业宁 Department of Physics Nanjing University Department of Physics Nanjing University? INTRODUCTION LiNbO_3 is an interesting crystal in view of its piezoelectrical electrooptical and nonlinear optical properties. It has potential applications in the laser and microwaveacoustic fields. Based on the investigations the authors held that the anomalous birefrigence behavior along C axis of LiNb O_2 near 75℃ may be attributed to the unkown phase transition instead of the cause supposed by et al. However the change of the crystal structure involved is still open.

Chinese Science Bulletin 1983年 第2期28卷 213-215页
作者: 沈之烨 刘蕙芳 Dalian Institute of Chemical Physics Academia Sinica Dalian Institute of Chemical Physics Academia Sinicahe vibration-rotation spectra of N_2O are among the most thoroughly investigated IR spectra in the literature. Recently the observation made by C. Amiot et al. gave molecular constants with great precision. There is however no information yet on the Q branch of the 21~10-01~10 band.
