抄録
The influence of external pressure on the electrical-resistivity behavior of Ce2Pd3Si5, recently reported to order antiferromagnetically below (TN=) 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 TN 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 2.3 K like a nonmagnetic Kondo lattice at 8 GPa with a distinct feature attributable to Kondo coherence effects.
