我们提出了第一个系统的研究多晶Sr2MoO4作为电子类似物的自旋三重态超导体Sr2RuO4。观察到了泡利顺磁磁化率和金属的比热、电阻率行为。从结果推导出的费米能级D（EF）的态密度是约三分之一小于Sr2RuO4。任何迹象的超导性固有的Sr 2 MoO 4尚未观察到下降到25 mK，这可能对应于较小的D（EF）。讨论了Sr2MoO4和Sr2RuO4电子态差异的原因.
We present the first systematic study on polycrystalline Sr 2 MoO 4 as an electronic analogue to the spin-triplet superconductor Sr 2 RuO 4 . The Pauli paramagnetic susceptibility and metallic behaviors of specific heat and electrical resistivity have been observed. The density of states at the Fermi level D(E F ) deduced from the results is about three times smaller than that of Sr 2 RuO 4 . Any indication of superconductivity intrinsic to Sr 2 MoO 4 has not been observed down to 25 mK, which may correspond to the smaller D(E F ). We discuss the origin of the difference in electronic states between Sr 2 MoO 4 and Sr 2 RuO 4 .
