Abstract

Itinerant and local moment magnetism have substantively different origins, and require distinct theoretical treatment. A unified theory of magnetism has long been sought after, and remains elusive, mainly due to the limited number of known itinerant magnetic systems. In the case of the two such examples discovered several decades ago, ZrZn21 and Sc3In2, the understanding of their magnetic ground states draws on the existence of 3d electrons subject to strong spin fluctuations. Similarly, in Cr3, an elemental itinerant ferromagnetic (IAFM) with a spin density wave (SDW) ground state its 3d character has been deemed crucial to it being magnetic. Here we report the discovery of the first IAFM with no magnetic constituents, TiAu, with no Ti d electrons. Ti is shown to be close to the Ti4+ 3du0^4s0 state, therefore this new IAFM challenges the currently limited understanding of weak itinerant antiferromagnetism, while providing long sought-after insights into the effects of spin fluctuations in itinerant electron systems.
