Quantum spin liquids form a novel class of matter where, despite the existence of strong
exchange interactions, spins do not order down to the lowest measured temperature …

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

In the ferromagnetic insulator with the Dzyaloshinskii-Moriya interaction, we theoretically
predict and numerically verify a topological magnon insulator, where the charge-free …

Magnetic susceptibility, NMR, muon spin relaxation, and inelastic neutron scattering
measurements show that kapellasite, Cu 3 Zn (OH) 6 Cl 2, a geometrically frustrated spin …

A promising route towards the realization of chiral spin liquids is the quantum melting of
classically noncoplanar spin states via quantum fluctuations. In the classical realm, such …

Après avoir introduit la thématique du magnétisme fortement frustré par le biais de la
recherche d'un état liquide de spin quantique au-delà de la dimension 1, nous discutons en …

Topological states of matter have been a subject of intensive studies in recent years
because of their exotic properties such as the topologically protected edge and surface …

Today, seeking new materials for tailor-made applications and new devices leads to explore
the potential offered by various kinds of functional building blocks. Hence, it concerns not …

The kagome-bilayer material Fe 3 Sn 2 has recently been shown to be an example of a rare
class of magnet—a frustrated ferromagnetic metal. While the magnetism of Fe 3 Sn 2 …

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 …
