Kondo effect on electrical properties of TmIn3

We presented results of electrical resistivity, magnetoresistivity and Seebek effect measurements done in the paramagnetic state of an antiferromagnetically ordering intermetallic compound TmIn₃. It was found that the magnetic part of the electrical resistivity showed maximum at 18 K and the lgT dependence in temperature range 20<T<100 K. The magnetoresistivity was negative. The transversal magnetoresistivity fulfilled the single-ion Kondo scaling for temperatures 2<(T+0.5 K)<28 K. Thermoelectricpower displayed a sharp minimum at 10 K. Electrical properties indicated that TmIn₃ is likely a dense Kondo system.
