Thermal Hall Effect of Spin Excitations in a Kagome Magnet.

At low temperatures, the thermal conductivity of spin excitations in a magnetic insulator can exceed that of phonons. However, because they are charge neutral, the spin waves are not expected to display a thermal Hall effect. However, in the kagome lattice, theory predicts that the Berry curvature leads to a thermal Hall conductivity κ(xy). Here we report observation of a large κ(xy) in the kag...

Title Chiral Spin Liquid in a Frustrated Anisotropic Kagome

A metamagnetic 2D copper(ii)-azide complex with 1D ferromagnetism and a hysteretic spin-flop transition.

Compound [Cu(3)(N(3))(6)(DMF)(2)](n) () was initially obtained in a serendipitous way during efforts to prepare a Cu(II)/N(3)(-)/Mebta coordination polymer (Mebta = 1-methylbenzotriazole). With the identity of established by single-crystal crystallography, a rational preparative route to this complex was designed and carried out by reacting Cu(ClO(4)).6H(2)O with two equivalents of NaN(3) in DM...

Spin-liquid phase in a spin-1/2 quantum magnet on the kagome lattice.

We study a model of hard-core bosons with short-range repulsive interactions at half filling on the kagome lattice. Using quantum Monte Carlo numerics, we find that this model shows a continuous superfluid-insulator quantum phase transition, with exponents z=1 and nu approximately 0.67(5). The insulator, I*, exhibits short-ranged density and bond correlations, topological order, and exponential...

Magnetic charge and ordering in kagome spin ice.

We present a numerical study of magnetic ordering in spin ice on kagome, a two-dimensional lattice of corner-sharing triangles. The magnet has six ground states and the ordering occurs in two stages, as one might expect for a six-state clock model. In spin ice with short-range interactions up to second neighbours, there is an intermediate critical phase separated from the paramagnetic and order...
