Phys. Rev. Lett. 84, 5872–5875 (2000)Theory of “Ferrisuperconductivity” in U1-xThxBe13Received 8 July 1999; published in the issue dated 19 June 2000 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 xc1≈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. © 2000 The American Physical Society URL:
