Sažetak
This is the first study of the effect of pressure on transition metal dichalcogenides intercalated by atoms that order magnetically. The material is Co1/3NbS2, a layered system where the intercalated Co atoms order antiferromagnetically at TN = 26 K at ambient pressure. At ambient pressure we measure dc-resistivity , thermoelectric power and thermal conductivity. We find that magnetic transition shows as a pronounced peak in , as well as a kink in the dc-resistivity. The effect of ordering on the thermal conductivity is rather small but, surprisingly, more pronounced in the lattice contribution than in the electronic contribution to . Under pressure the resistivity increases in the high temperature range, contrary to all previous measurements in other layered transition metal dichalcogenides (TMD). On the low temperature side, the strong dependences of thermopower and resistivity on pressure are observed below TN, which, in turn, also depends on pressure at rate of dTN/dp ~ -1 K/kbar. Several possible microscopic origins of the reduction of the ordering temperature and the evolution of the transport properties with pressure are discussed. The explanation is tentatively set into the framework of competing Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction and Kondo screening.
