Popis:	We report the determination of the Dzyaloshinsky-Moriya interaction, the dominant magnetic anisotropy term in the kagome spin-1/2 compound ZnCu3 OH 6 Cl2 . Based on the analysis of the high-temperature electron spin resonance (ESR) spectra, we find its main component jDz j 15 1 K to beperpendicular to the kagome planes. Through the temperature dependent ESR linewidth, we observe a building up of nearest-neighbor spin-spin correlations below 150 K.
