^{59}Co-Nuclear Quadrupole Resonance and Nuclear Magnetic Resonance studies on YCoGe --- Comparison between YCoGe and UCoGe ---
摘要：
我们对铁磁超导体UCoGe的参考化合物YCoGe进行了^{59} Co核四极共振（NQR）和核磁共振（NMR）研究，以研究Co位的磁性。磁和超导转变没有观察到下降到0.3 K，但发现在YCoGe的常规金属行为，虽然它的晶体结构是类似的UCoGe。从两种化合物的实验结果比较，在UCoGe中观察到的铁磁性和超导电性起源于U-5 f电子。
英文摘要：
We have performed ^{59}Co-nuclear quadrupole resonance (NQR) and nuclear magnetic resonance (NMR) studies on YCoGe, which is a reference compound of ferromagnetic superconductor UCoGe, in order to investigate the magnetic properties at the Co site. Magnetic and superconducting transitions were not observed down to 0.3 K, but a conventional metallic behavior was found in YCoGe, although its crystal structure is similar to that of UCoGe. From the comparison between experimental results of two compounds, the ferromagnetism and superconductivity observed in UCoGe originate from the U-5f electrons.
