Title: Investigation of UBe/sub 13/ and other beryllium and uranium compounds in normal and superconducting states

Abstract

The Hall U /SUB 1x1g/ (H), magnetoresistance p(H), magnetization in the superconducting state M(H), and the second superconducting critical magnetic field of UBe/sub 13/ have been investigated. It is found that U /SUB 1x1g/ (H) is not linear, but has a maximum near H = 70 kOe at T = 1.9 K. When the temperature rises from 1.9 to 100 K, the Hall coefficient R(H ..-->.. 0) decreases about 20 times from 2.5 x 10/sup -10/ to 1.35 x 10 /sup -11/ ..cap omega..-cm/Oe. The rise of the magnetic field causes a strong decrease of the electrical resistance: at T = 1.7 K, /rho/(0)//rho/(210 kOe) approx. = 5.8. From the H /SUB c2/ investigation for single crystals it can be seen that near T /SUB c/ the anisotropy of H /SUB c2/ is absent (it becomes visible only upon lowering T to 0.9 T /SUB c/ ). The M (H) /SUB T/ < /SUB T/ /SUB c/ is similar to the typical dependence for type 11 superconductors. The thermodynamic critical field H /SUB c/ (O)approx. = 1 kG, the Ginzburg-Landau parameter /chi/ approx. = 60, and the penetration depth lambda approx. = 4.10/sup -5/ cm. The effects of alloying amore » small quantity of iron and of neutron irradiation are investigated. The effects of alloying with other compounds of U and Be are also discussed. It is possible to suppose that UBe/sub 13/ has two groups of carriers, ''heavy'' and ''light,'' with the anomalous properties of UBe/sub 13/ caused by the specificity of the interaction between these two groups of carriers.« less
