Abstract:
Magnetization of Bi0:9-xGdxLa0:1FeO3 (x=0.3, 0.5, 0.6 and 0.7) is reported. An abnormal negative magnetization appears in the temperature-dependent magnetization curves, and the temperature-dependent coercive field shows a maximum in the vicinity of the compensation temperature where the total magnetization is zero. These results suggest that in the ferrimagnetic-like Bi0:9-xGdxLa0:1FeO3 system the Gd and Fe magnetic sublattices are coupled antiferromagnetically.

空气/甲醇界面和频振动光谱的定量偏振分析
吴慧,张文凯,干为,崔执凤*,王鸿飞*
摘要:
对空气/甲醇液体界面的和频振动光谱进行了定量的理论分析.虽然甲醇的红外和Raman光谱中都具有明显的反对称伸缩振动峰,但该光谱峰在界面和频振动光谱中却从未被观测到.利用已知的甲醇液体的红外和Raman光谱对和频振动光谱的键极化模型进行了修正,从而对此实验现象进行了定量的解释.此修正可以广泛地应用于界面和频振动光谱的研究中.
