Zusammenfassung:
The evolution of antiferromagnetic order in the Kondo system Ce2Ir3Ge5 was investigated by measurements of the electrical resistivity under hydrostatic pressure. At low pressure (p < 1.0 GPa), T-N = 9.1 K and the resistivity is nearly independent on pressure. Applying higher pressure decreases TN slowly up to 2.0 GPa, followed by a step-like reduction of T-N from 7.5 to 3.9 K over the range 2.0 GPa< p< 2.3 GPa. TN is depressed more slowly again with increasing pressure above 2.3 GPa. (C) 2002 Elsevier Science B.V. All rights reserved.
