CeRuSn: a strongly correlated material with nontrivial topology
M. Sundermann, F. Strigari, T. Willers +14
Topological insulators form a novel state of matter that provides new opportunities to create unique quantum phenomena. While the materials used so far are based on semiconductors,…
Electronic and Spin States of SrRuO3 Thin Films: an X-ray Magnetic Circular Dichroism Study
S. Agrestini, Z. Hu, C. -Y. Kuo +14
We report a study of the local magnetism in thin films of SrRuO3 grown on (111) and (001) oriented SrTiO3 substrates using x-ray magnetic circular dichroism spectroscopy (XMCD) at…
SmO thin films: a flexible route to correlated flat bands with nontrivial topology
Deepa Kasinathan, Klaus Koepernik, L. H. Tjeng +1
Using density functional theory based calculations, we show that the correlated mixed-valent compound SmO is a 3D strongly topological semi-metal as a result of a 4-5 band in…
