论文摘要
在这项工作中，我们报告了EUSN $ _2 $的宽带铁磁共振光谱，为$ _2 $在不同温度下的单晶，以及磁化测量和结构表征。我们观察到欧盟子晶格中A型抗铁磁旋转相位的常规集体声音共振模式，并过渡到订购温度以上的顺磁共振。此外，我们观察到可重复定义明确的光谱线。附加线的起源仍不清楚。但是，其温度依赖性将其归因于欧盟亚晶格中的磁性。
In this work, we report the broad-band ferromagnetic resonance spectroscopy of EuSn$_2$As$_2$ single crystals at different temperatures in combination with magnetization measurements and structural characterization. We observe conventional collective acoustic resonance mode of the A-type antiferromagnetic spin-flop phase in the Eu sub-lattice, and its transition to the paramagnetic resonance above the ordering temperature. Furthermore, we observe reproducibly additional well-defined spectral line. The origin of the additional line remains unclear. However, its temperature dependence attributes it to magnetism in the Eu sub-lattice.
