Abstract

A thaw in the spin ice Chiral spin liquids are a long-sought hypothetical class of spin liquids — spin systems in frustrated magnets that neither freeze nor order even at T = 0 — in which time-reversal symmetry is macroscopically broken even in the absence of an applied magnetic field or any magnetic dipole long-range order. Machida et al. report an investigation of the magnetic and transport properties of the metallic frustrated magnet Pr2Ir2O7, observing a spontaneous Hall effect in the absence of uniform magnetization and at zero magnetic field. The data and analysis suggests that a chiral spin-liquid phase is induced by melting of a spin ice and the formation of chiral spin textures.
