Abstracts

EN

The thermal conductivity of the quasi-one-dimensional S = 5/2 Heisenberg antiferromagnet CsMnCl_3·2H_2O with the intrachain interaction J/k_{B} = 3 K was experimentally studied at temperatures from 2 to 25 K. The data analysis performed within the Debye model with the relaxation-time approximation unambiguously indicates the presence of the scattering of phonons on magnetic subsystem.
