Epitaxial growth and electronic properties of mixed valence YbAl3 thin films

Shouvik Chatterjee, Suk Hyun Sung, David J. Baek +3

We report the growth of thin films of the mixed valence compound YbAl${}_3$ on MgO using molecular-beam epitaxy. Employing an aluminum buffer layer, epitaxial (001) films can be gr…
