| Abstract: | The electrical resistivity of the Kondo system (La, Ce)B6 has been measured in longitudinal and transversal magnetic fields up to 6 Tesla in the temperature range 0.04–20K. Corresponding to the strong increase of the resistivity with decreasing temperature the alloys show a very large negative magnetoresistivity with a Kondo temperatureT
K
=1.05K and a Kondo magnetic fieldB
K
=1.1 Tesla. The observed anisotropy of the resistivity due to the magnetic field direction cannot be explained well by existing theories. |
