Implications of Tc variation in UBe13 for a possible Fulde-Ferrell-Larkin-Ovchinnikov phase
H. A. Radovan, R. J. Zieve, J. S. Kim +1
We measure the heat capacity of UBe13 with an unusually low Tc for a polycrystal. We find an upturn in the upper critical field Hc2(T) below about Tc/2, much as for higher-Tc sampl…

Heavy-ion irradiation of UBe13 superconductors
H. A. Radovan, E. Behne, R. J. Zieve +4
We irradiate the heavy fermion superconductors (U,Th)Be_13 with high-energy heavy ions. Damage from the ions affects both heat capacity and magnetization measurements, although muc…

Stable Vortex Configurations in a Cylinder
R. J. Zieve, L. A. K. Donev
We calculate stable arrangements for a single superfluid vortex pinned to the wall of a stationary cylindrical container. We find that, independent of the details of the pinning si…
