分析了有机超导体θ-(BEDT-TTF) 2i3中de Haas-van Alphen振荡的温度场依赖性。对于慢振荡和快振荡，回旋加速器的质量估计分别为2.0 m e和3.6 m e。从费米面几何的角度讨论了磁击穿效应的指示。结果与红外反射光谱和经验紧结合带计算结果进行了比较。
Analysis of the temperature and field dependence of the de Haas-van Alphen oscillations in an organic superconductor θ-(BEDT-TTF) 2 I 3 is presented. The cyclotron masses are estimated to be 2.0 m e and 3.6 m e for slow and fast oscillations, respectively. The indication of magnetic breakdown effect is discussed in terms of the geometry of the Fermi surface. The result is compared with those of the infrared reflectance spectra and the empirical tight-binding band calculations.
