Abstract

The thermal conductivity and heat capacity of single crystals of 2D Heisenberg antiferromagnet K2V3O8 were measured in magnetic field. The thermal transport option from Quantum Design was tested using a variety of thermal conductivity standards for utilizing in four wire thermal conductivity measurements. The zero field thermal conductivity data was found to be consistent with resonant scattering of photons by magnons near the zone boundary. The application of magnetic field greater than 1 T, was reported to produce a new magnetic ground state with substantial heat transport by wavelength magnons.
