The influence of external pressure on the electrical-resistivity behavior of Ce 2 Pd 3 Si 5 , recently reported to order antiferromagnetically below (T N ϭ) 8.2 K, has been investigated in the temperature interval 2.5-300 K employing a cubic anvil pressure cell up to 8 GPa. We find that T N remains nearly constant below 4 GPa, beyond which there is a sharp decrease, which establishes that this compound lies at the peak of Doniach's magnetic phase diagram. Apparently this compound behaves above
