Highly Anisotropic Charge Dynamics and Spectral Weight Redistribution in the Trilayer Nickelate La $_{4}$ Ni $_{3}$ O $_{10}$

Zhe Liu, Jie Li, Deyuan Hu +10

We study the $ab$ -plane and $c$ -axis charge dynamics of La $_{4}$ Ni $_{3}$ O $_{10}$ using optical spectroscopy. While a pronounced Drude profile, i.e. metallic response, is observed i…

Growth of (Cu,C)Ba $_{2}$ Ca $_{2}$ Cu $_{3}$ O $_{9 \pm I^´}$ thin films on flexible Hastelloy tapes

Meng-Jun Ou, Yuecong Liu, Yi Wang +1

The applications of superconducting cable or magnet require that the superconductors are made into wires or tapes. For cuprate superconductors, this is a big challenge because of t…
