Abstract

We use time-dependent Ginzburg–Landau theory in a three-dimensional model, including thermal noise, to analyze angle-dependent Hall resistivity and longitudinal resistivity of type-II superconductor. The Hall resistivity and longitudinal resistivity are calculated as functions of temperature, magnetic field and the angle $θ$ between the magnetic field and the ab-plane in the vortex-liquid regime. Our theoretical calculations within a self-consistent fluctuation approximation for MgB₂ and HgBa₂CaCu₂O₆ materials are in good agreements with the experimental findings for both below and above the critical temperature $T_{c}$ . We observe that when the field angle decreases, the transition temperature increases and the magnitude of longitudinal resistivity decreases, which is qualitatively comparable to decrease of the perpendicular field component. However, when the magnetic field direction approaches the layer surface, it shows a clear different effect from that of a perpendicular field with the same normal component.

II 型超导体随角度变化的霍尔电阻率和纵向电阻率

我们在一个包含热噪声的三维模型中使用随时间变化的金兹堡-朗道理论，分析了 II 型超导体随角度变化的霍尔电阻率和纵向电阻率。霍尔电阻率和纵向电阻率是作为温度、磁场以及涡流液态下磁场与 ab 平面夹角 θ 的函数来计算的。在自洽波动近似条件下，我们对 MgB2 和 HgBa2CaCu2O6 材料的理论计算结果与低于和高于临界温度 Tc 的实验结果非常吻合。我们观察到，当磁场角度减小时，转变温度升高，纵向电阻率的大小减小，这与垂直磁场分量的减小有本质上的相似性。然而，当磁场方向接近磁层表面时，其效果明显不同于具有相同法向分量的垂直磁场。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
