为了研究CeRu 2单晶的超导混合态性质，我们测量了磁通流态下的电阻率和霍尔电阻率。我们发现，峰值效应，讨论有关的富尔德-费雷尔-拉金-奥夫钦尼科夫（FLLO）阶段，持续到一个更高的温度比以前报道的磁化强度和弹性测量，这与原来的FFLO理论相矛盾。我们估计钉扎力密度的磁通流输运性质的依赖于电流密度。我们还报告了正常状态下的输运性质和磁化强度，并将它们与最近的一份报告中提出的可能的多相超导性进行了比较。
We have measured the electrical resistivity and Hall resistivity in the flux flow state to investigate the superconducting mixed state properties in a CeRu 2 single crystal. We found that the peak effect, discussed in relation to the Fulde-Ferrel-Larkin-Ovchinnikov (FLLO) phases, persists up to a higher temperature than that reported previously based on magnetization and elastic measurements, which contradicts with the original FFLO theories. We have estimated the pinning force density from the dependence of the flux flow transport properties on the current density. We also report the normal state transport properties and the magnetization and compare them with those given in a recent report in which possible multiple phase superconductivity was proposed.
