我们研究了单晶的物理性质，这些单晶表现出由 V 态中的轨道和电荷自由度引起的三个不同的相。通过磁化率和核磁共振测量发现，该系列化合物的低温相具有自旋单线态特征。我们还从电阻率和电导率谱中发现，这些化合物在低温相中随着V三聚而变得严重各向异性，这表明V态的轨道有序性导致了该系列化合物电子结构的各向异性。
We studied the physical properties ofsingle crystals, which exhibit three different phases caused by the orbital and charge degrees of freedom in Vstates. We found from the magnetic susceptibility and the NMR measurement that the low-temperature phase of this series of compounds is characterized by the spin-singlet state. We also found from the electrical resistivity and optical conductivity spectra that these compounds become heavily anisotropic in the low-temperature phase with V trimerization, indicating that the orbital ordering of Vstates causes the anisotropy of the electronic structure of this series of compounds.
