Thermodynamic and Transport Properties of YTe3, LaTe3 and CeTe3
Ru, N..
Measurements of heat capacity, susceptibility, and electrical resistivity are presented for single crystals of the charge density wave compounds YTe3, LaTe3, and CeTe3. The materials are metallic to low temperatures, but have a small density of states due to the charge density wave gapping large portions of the Fermi surface. CeTe3 is found to be a weak Kondo lattice, with an antiferromagnetic ground state and TN=2.8 K. The electrical resistivity of all three compounds is highly anisotropic, con... Show Full Abstract
Measurements of heat capacity, susceptibility, and electrical resistivity are presented for single crystals of the charge density wave compounds YTe3, LaTe3, and CeTe3. The materials are metallic to low temperatures, but have a small density of states due to the charge density wave gapping large portions of the Fermi surface. CeTe3 is found to be a weak Kondo lattice, with an antiferromagnetic ground state and TN=2.8 K. The electrical resistivity of all three compounds is highly anisotropic, confirming the weak dispersion perpendicular to Te planes predicted by band structure calculations. Show Partial Abstract
