Abstract

Magnetoresistivity measurements of polycrystalline U₂Rh₂Sn in an applied magnetic field of 8.29 T reveal a sharp minimum at the antiferromagnetic transition temperature TN ≅ 20 K. The thermoelectric power of U₂Rh₂Sn exhibits negative values for temperatures T ≤ 24K. At T ≅ 4K, a large decrease in resistivity with lowering of temperature is observed for polycrystalline U₂Fe₂Sn. This anomaly originates from the occurrence of free tin on the grain boundaries of the sample giving a decrease in resistivity as a result of superconductivity.
