通过电阻率、磁化率和比热的测量，研究了三种CeNiSi2结构的CeTMX2化合物的基态。虽然CeNiSi2是一个中价体系，但我们在CePtSi2和CeNiGe2中观察到了在重费米子存在下的磁性有序。讨论了从111或122化合物到112化合物的重费密子形成的趋势。
The ground state of three CeTMX2compounds with CeNiSi2structure type was investigated by electrical-resistivity, magnetic-susceptibility and specific-heat measurements. Whereas CeNiSi2is an intermediate-valent system, we observe in CePtSi2and CeNiGe2magnetic ordering in the presence of heavy fermions. The trends in heavy-fermion formation on going from either the 111 or 122 to the 112 compounds are discussed.
