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 …

Recent improvements in ultra-high magnetic field generation and precise measurement
techniques have facilitated the study of the physical properties of magnetic materials under …

We present thermodynamic studies of a new spin-1/2 antiferromagnet containing undistorted
kagome lattices—barlowite Cu 4 (OH) 6 FBr. Magnetic susceptibility gives θ CW=-136 K …

Polymorphs of ZnCu3 (OH) 6Cl2 (herbertsmithite and kapellasite) and related cuprates
MCu3 (OH) 6Cl2 (M= Mg2+, Ca2+, Cd2+, Co2+, Fe2+, Mn2+ and Ni2+) with …

One of the key questions concerning frustrated lattices that has lately emerged is the role of
disorder in inducing spin-liquid-like properties. In this context, the quantum kagome …

We present the crystal structure and magnetic properties of Y3Cu9 (OH) 19Cl8, a
stoichiometric frustrated quantum spin system with slightly distorted kagome layers. Single …

Abstract Herbertsmithite ZnCu 3 (OH) 6 Cl 2 was initially proposed to have a “perfect” model
for the S= 1/2 kagomé antiferromagnet, but further investigations have revealed its intrinsic …

Electronic states with non-trivial topology host a number of novel phenomena with potential
for revolutionizing information technology. The quantum anomalous Hall effect provides spin …

Geometric frustration of magnetic ions can lead to a quantum spin liquid ground state where
long-range magnetic order is avoided despite strong exchange interactions. The physical …

We present the hydrothermal synthesis, as well as structural and chemical analysis, of single
crystals of EuCu 3 (OH) 6 Cl 3, Zn x Cu 4− x (OH) 6 (NO 3) 2 and haydeeite, and MgCu 3 …
