Abstract
We report zero-, longitudinal-, and transverse-field positive muon spin relaxation (μSR) measurements in single crystals of the heavy-fermion superconductor UBe13 [Tc=0.83(2)K]. Our zero-field measurements provide an upper limit for any quasistatic magnetic moments in this system below 100 K of 0.001μB, consistent with previous measurements on polycrystals. From the transverse-field measurements we find a lower bound for the London penetration depth λL=1210nm. This value implies a lower limit for the effective mass consistent with the low-temperature specific heat.
