The pressure effect on magnetism in CeTe1.82

초록

We report the pressure effect of the normal-state transport and magnetic properties of CeTe1.82 up to 9 kbar. We found that the applied pressure increases the Kondo temperature (T-K* similar to 170 K), which is associated with the two-dimensional motion of carriers confined within the Te plane. Both the short-range ferromagnetic ordering temperature (T-SRF similar to 6 K) and the long-range antiferromagnetic transition temperature (T-N similar to 4.3 K) are slightly increased with pressure. We suggest that the application of pressure enhances coupling between the 4f and conduction electrons. While applying the magnetic field, a large magnetoresistance is observed in the vicinity of T-SRF, which is analogous to that at ambient pressure.
