Multiple localized-itinerant dualities in magnetism of 5f electron systems. The case of UPt${}_2$Si${}_2$

L. M. Sandratskii, V. M. Silkin, L. Havela

The paper deals with the U based compound UPt${}_2$Si${}_2$ (UPS). The material was first treated as a localized 5f-electron system. Later, an opposite opinion of a predominantly itine…
