· J. Appl. Phys.; (United States)
Measurements of the ac electrical resistance as a function of temperature and applied magnetic field R(T,H) were made for various compositions x < or approx. =0.03 in the mixed binary system (U/sub 1-x/Th/sub x/)Be/sub 13/. All samples within this range of x exhibit heavy Fermion superconductivity with a superconducting transition temperature T/sub c/ that is rapidly suppressed by the substitution of Th for U. The shape of the upper critical field curve H/sub c/2(T) determined from the R(T,H) data is similar for all compositions with a very large initial slope (-dH/sub c/2/dT)/sub T//sub c/.
