“…d-and f -moments (e.g. RECrSb 3 series [4]). One particularly intriguing avenue for research are conductors with non-collinear static spin structures, as their chirality can introduce a Berry phase in the electronic scattering and lead to spin-dependent effects, such as extraordinarily large values of the anomalous Hall effect (AHE).…”

Frustrated itinerant ferromagnets, with non-collinear static spin structures, are an exciting class of material as their spin chirality can introduce a Berry phase in the electronic scattering and lead to exotic electronic phenomena such as the anomalous Hall effect (AHE). This study presents a reexamination of the magnetic properties of Fe(3)Sn(2), a metallic ferromagnet, based on the two-dimensional kagome bilayer structure. Previously thought of as a conventional ferromagnet, we show using a combination of SQUID (superconducting quantum interference device) measurements, symmetry analysis and powder neutron diffraction that Fe(3)Sn(2) is a frustrated ferromagnet with a temperature-dependent non-collinear spin structure. The complexity of the magnetic interactions is further evidenced by a re-entrant spin glass transition ([Formula: see text] K) at temperatures far below the main ferromagnetic transition (T(C) = 640 K). Fe(3)Sn(2) therefore provides a rare example of a frustrated itinerant ferromagnet. Further, as well as being of great fundamental interest our studies highlight the potential of Fe(3)Sn(2) for practical application in spintronics technology, as the AHE arising from the ferromagnetism in this material is expected to be enhanced by the coupling between the conduction electrons and the non-trivial magnetic structure over an exceptionally wide temperature range.

“…Despite this, the work on frustrated ferromagnets with localized spins, the spin ices [25,26,27,28,29] shows clearly the wealth of exotic behavior that can be hosted by frustrated ferromagnetic states [30,31]. The challenge is now to develop an understanding of how geometric frustration enriches the physics that results from coupling the dual characters of localized spins and itinerant electrons, and effects such as the Kondo effect [32] or the competition between itinerant and dipole anisotropies [33,34,35].…”

We have investigated magnetic and transport properties of the kagomé-bilayer ferromagnet Fe 3 Sn 2 . A soft ferromagnetism and a large anomalous Hall effect are observed. The saturated Hall resistivity of Fe 3 Sn 2 is 3.2 µΩcm at 300 K, which is almost 20 times higher than that of typical itinerant-ferromagnets such as Fe and Ni. The anomalous Hall coefficient R s is 6.7×10 −9 Ωcm/G at 300 K, which is three orders of magnitude larger than that of pure Fe. R s obeys an unconventional scaling to the longitudinal resistivity, ρ xx , of R s ∝ ρ 3.3 xx . Such a relationship cannot be explained by the skew and/or side-jump mechanisms and indicates that the origin of the anomalous Hall effect in the frustrated magnet Fe 3 Sn 2 is indeed extraordinary.

Rare Earth (re) based intermetallics are a fascinating class of inorganic compounds due to the presence of highly localized f‐electrons. Among the ternary intermetallics, RETX3 (RE – Rare Earth, T – Transition metals, X – 13–15th elements of the main groups) is one of the most widely studied RE‐based intermetallic families in terms of diverse crystal structures as well as physical properties. This perspective presents a brief account of different structural variations observed in this family of compounds. We have also discussed structure‐property correlations in selected compounds in this series that show interesting physical properties such as spin‐glass behavior, superconductivity, heavy fermion behavior, Kondo behavior, etc. The origin of different physical properties of these compounds is also discussed in brief by correlating their crystal structures.
