Crystallization of heavy fermions via epitaxial strain in spinel LiV${}_2$O${}_4$ thin film

U. Niemann, Y. -M. Wu, R. Oka +6

The mixed-valent spinel LiV${}_2$O${}_4$ is known as the first oxide heavy-fermion system. There is a general consensus that a subtle interplay of charge, spin, and orbital degrees…
