摘要：

The quasiparticle excitations in the mixed state of Cd2Re2O7 have been studied by means of muon spin rotation/rclaxation (muSR). The temperature dependence of the magnetic penetration depth (lambda) is consistent with a nearly isotropic superconducting order parameter, although a slight discrepancy which is dependent on the details in the analysis may be present. This is also supported by the relatively weak field dependence of lambda.
