Terahertz Electrodynamics of Mixed-Valent YbAl${}_3$ and LuAl${}_3$ Thin Films

D. Barbalas, S. Chatterjee, D. G. Schlom +2

We present THz measurements of thin films of mixed-valent YbAl${}_3$ and its structural analogue LuAl${}_3$. Combined with traditional Fourier transform infrared (FTIR) spectroscopy, t…
