Thermal conductivity of spin gap antiferromagnets

The thermal conductivity of spin-gap antiferomagnets (SG AFMs) is a tool that probes their spin excitations and spins-phonons interaction. A variety of phenomena are observed: for example, in various strontium-cuprates thermal conductivity strongly enhances due to the opening of the heat channel carried by either magnons or spinonsa. In spin-Peierls compounds the thermal conductivity exhibits rather unusual double peak features at low temperatures, explained as a ngerprint of the spin-phonon resonance scatteringb. The thermal conductivity of strongly frustrated systems also shows the existence of spin-phonon resonance at low temperatures. We present the study of the thermal transport of several SG AFMs: (i) of copper-tellurides, quasi-0D geomatrically frustrated compounds with S=1/2, (b) of a "zig-zag" frustrated spin ladder system LiCu2O2 (S=1/2), and (c) quasi-2D S=1 system nickel-telluride. We nd that the thermal conductivity of these systems exhibit features typical for spin-phonon resonance coupling, gradually decreasing as the dimensionality of the systems increase
