Abstract

We have explored the low-energy dynamics in the half-doped Eu0.5Sr0.5MnO3 using terahertz time domain (TDS) spectroscopy. Observation of a finite frequency peak structure in optical conductivity at around ∼4meV suggests low-energy excitation, presumably the charge-density waves.

半掺杂锰矿Eu0.5Sr0.5MnO3的低能激发
利用太赫兹时域(TDS)光谱研究了半掺杂Eu0.5Sr0.5MnO3的低能动力学。在约4meV的光电导率中观察到的有限频率峰值结构表明低能激发,可能是电荷密度波。
