MgB_2超导体输运特性的研究

Study on the Transport Properties of Superconductor MgB_2

文中对 Mg B2 超导体的制备过程 ,对其同位素效应、电阻率、I- V曲线、热电势、电导涨落效应、能隙、霍尔效应、热重 -差热分析实验等输运特性进行了较全面的综述 ,并讨论了在 Mg B2 超导体基础上的元素替代效应。

This paper makes an analysis and study of the preparation process, boron isotope, the temperature dependent resistivity and thermopower effect of the fluctuation magnetoconductance, energy gap, hall effect, TG-DTA of the MgB 2 superconductor. And the result of M-doped Mg 1-xM xB 2 superconductor by solid-state reaction was discussed. It was helpful for the further research in superconductivity process.
