The temperature dependence of density, normal spectral emissivity, heat capacity at constant pressure, and thermal conductivity of the V melt were measured with high accuracy using electromagnetic levitation in a static magnetic field. Surface vibration, translational motion, and convection of the electromagnetically levitated droplet sample were suppressed by the magnetic field. In the measurement of thermal conductivity, convection in the V-melt was sufficiently suppressed by the application of a field of 7 T or higher. In this study, the measured emissivity and thermal conductivity are compared with those evaluated using the free-electron models (Drude model and Wiedemann–Franz rule). Correlations between the density of states and thermal diffusivity at the Fermi energy of transition metals in the liquid state are investigated and the applicability of Mott's s–d scattering model is discussed.

使用静磁场中的电磁悬浮高精度测量了 V 熔体的密度、正常光谱发射率、恒压热容和热导率的温度依赖性。磁场抑制了电磁悬浮液滴样品的表面振动、平移运动和对流。在导热率的测量中，通过施加7T或更高的场，V-熔体中的对流被充分抑制。在本研究中，将测得的发射率和导热率与使用自由电子模型（德鲁德模型和维德曼-弗朗兹规则）评估的发射率和导热率进行了比较。研究了液态过渡金属的态密度和费米能级热扩散率之间的相关性，并讨论了 Mott s – d散射模型的适用性。
