论文摘要
在此简短说明中,我们报告了第一次无弹性中子散射(INS)研究SR $ _3 $ ir $ _2 $ o $ $ _7 $中的高能磁激发。我们观察到$ \ sim $ 80 mev和$ \ sim $ 180 mev之间的激发。激发的峰位置与通过共振非弹性X射线散射(RIX)测量确定的单个木核的分散一致。因此,我们的结果表明,INS和RIX可以观察到偶然氧化物中相同的激发,就像la $ _2 $ cuo $ _4 $一样。
In this short note, we report on the first inelastic neutron scattering (INS) study on high-energy magnetic excitations in Sr$_3$Ir$_2$O$_7$. We observed excitations between $\sim$80 meV and $\sim$180 meV. The peak position of the excitations is consistent with the dispersion of a single magnon determined by resonant inelastic X-ray scattering (RIXS) measurement. Thus, our results demonstrate that INS and RIXS observe identical excitations in iridate oxides, as in La$_2$CuO$_4$.
