The thermal conductivity of the magnetically frustrated, ferroelectric YMnO3 was investigated. Single crystalline YMnO3 was grown using the floating method, and polycrystalline specimens were synthesized with the help of a standard solid-state reaction. Thermal conductivity k(T) was measured using steady state method and heat capacity was measured using a relaxational method. An isotropic suppression in the cooperative paramagnetic state was observed followed by a sudden increase upon magnetic ordering.
