Abstract

We construct a two component Ginzburg-Landau theory with coherent pair motion and incoherent quasiparticles for the phase diagram of U1-xThxBe13. The two staggered superconducting states live at the Brillouin zone center and the zone boundary and coexist for temperatures T ≤ TC2 at concentrations xcl ≈ 0.02 ≤ x ≤ xc2 ≈ 0.04. We predict below TC2 the appearance of a charge density wave (CDW) and Be-sublattice distortion. The distortion explains the muon spin relaxation anomaly; Th-impurity mediated scattering of ultrasound to CDW fluctuations explains the attenuation peak.
