论文摘要
我们使用通量法报告了SMBI的高质量单晶生长。该化合物以空间群FM3M的形式在简单的岩盐结构中结晶。单晶体的立方结构通过LAUE衍射模式证实。磁化率的测量结果显示出尖锐的抗磁磁性，NEEL温度为9K。SM 3D的核心水平光发射光谱研究已使用单色AL Kalpha源进行。我们观察到由于恒阳态效应而引起的实验光谱中的多个特征 - SM 4F -BI 6P状态之间杂交的标志。还观察到强烈的卫星特征可能是由于围绕耦合引起的混合价值。在SM 3D核心水平光谱中未观察到表面构成差异的特征。
We report high quality single crystalline growth of SmBi using flux method. The compound crystallizes in the simple rock salt structure with space group Fm3m. The cubic structure of the single crystal was confirmed by Laue diffraction pattern. The magnetic susceptibility measurements reveal sharp antiferromagnetic order with Neel temperature of 9 K. The core level photoemission spectroscopy study of Sm 3d has been performed using monochromatic Al Kalpha source. We observe multiple features in the experimental spectra due to fonal state effect - a signature of hybridization between Sm 4f - Bi 6p states. Intense satellite features are also observed presumably due to mixed valency arising from Kondo coupling. No signature of surface-bulk difference is observed in the Sm 3d core level spectra.
