Reentrance of the induced diamagnetism in gold-niobium proximity cylinders
F. Bernd Mueller-Allinger, Ana Celia Mota
We discuss the magnetic response of gold-niobium proximity cylinders in the temperature range 100 μK<T<9 K. The temperature dependence of the susceptibility in the diamagnetic regi…
Strong vortex pinning in the low-temperature superconducting phase of (U_1-xTh_x)Be_13
Ana Celia Mota, Elisabeth Dumont, James L. Smith
We have found a sharp transition at T_c2=350 mK in the vortex creep rate of a single crystal of (U_1-xTh_x)Be_13 with T_c=523 mK (x=0.0275). For T<<T_c2, no creep of vortices is ob…
Transition into a low temperature superconducting phase of unconventional pinning in Sr_2RuO_4
A. C. Mota, E. Dumont, A. Amann +1
We have found a sharp transition in the vortex creep rates at a temperature T^\ast=0.05 T_c in a single crystal of Sr_2RuO_4 (T_{c}=1.03 K) by means of magnetic relaxation measurem…
Unconventional strong pinning in the low temperature phase of U_.9725Th_.0275Be_13
Elisabeth Dumont, Ana Celia Mota, James L. Smith
We investigated low field vortex dynamics in a single crystal of U_.9725Th_.0275Be_13. We found a sharp transition in the vortex creep rate at the lower transition temperature T_c2…
