Exceptional Ising Magnetic Behavior of Itinerant Spin-polarized Carriers in URu2Si2

Abstract

We show on the basis of electronic structure calculations that the uranium 5$f$ magnetic moment in URu${}_2$Si${}_2$ exhibits a unique Ising behavior, which surprisingly, arises from itinerant electronic states. The origin of the unusual Ising behavior is analyzed as due to the peculiar near-Fermi edge nested electronic structure of URu${}_2$Si${}_2$ involving its strong spin-orbit interaction. The Ising anisotropy has pertinent implications for theories applicable to explaining the Hidden Order phase in URu${}_2$Si${}_2$.
