Abstract
CeCu2Ge2 orders antiferromagnetically, T(N)approximately4K, and gamma(T) approximately 200 mJ/K2 mole near 0.5K and P=0. A pressure of 9.5 kbar has no measurable effect on T(N); reduces slightly the specific-heat anomaly at T(N); and reduces slightly gamma(T) below 0.7K. These effects of pressure are in striking contrast to the much stronger effects on other heavy-fermion compounds, e.g., CeAl3, URu2Si2 and CeCu2Si2.
