我们测量了在130 K下具有轨道有序性的大块单晶在单轴应变下的光学反射率谱。我们发现，随着压缩应变，特别是沿着轴，反射率光谱在室温下几乎以各向同性的方式变化，好像它改变到在较低的温度。该实验结果表明该化合物中轨道自由度和应变之间存在强耦合。
We measured the optical reflectivity spectra under applied uniaxial strain for bulk single crystals of, which exhibits orbital ordering at 130 K. We found that, with compressive strain, particularly, along theaxis, the reflectivity spectrum at room temperature changes almost in an isotropic manner as if it changes to that at lower temperatures. This experimental result indicates a strong coupling between the orbital degree of freedom and the strain in this compound.
