INVESTIGATION OF UBE13 AND OTHER BERYLLIUM AND URANIUM-COMPOUNDS IN NORMAL AND SUPERCONDUCTING STATES

The Hall voltage U//x//y(H), magnetoresistance rho (H), magnetization in the superconducting state M(H)m and the second superconducting critical magnetic field of UBe//1//3 have been investigated. It is found that U//x//y(H) is not linear, but has a maximum near H equals 70 kOe at T equals 1. 9 K. When the temperature rises from 1. 9 to 100 K, the Hall coefficient R(H yields 0) decreased about 20 tomes from 2. 5 multiplied by 10** minus **1**0 to 1. 35 multiplied by 10** minus **1**1 OMEGA -cm/Oe. The rise of the magnetic field causes a strong decrease of the electrical resistance: at T equals 1. 7 K. rho (0)/ rho (210 kOe) approximately equals 5. 8.
