Magnetic properties of UBe13 in its superconducting state
Alekseevskii N. E., Mitin A. V.
The magnetization has been measured as a function of the magnetic field, M{H), for a UBe13 single crystal at T< Tc. The results are used to determine the thermodynamic field ЯС(0.1К)= 920 Oe, the Ginzburg-Landau parameter к = 60, and the penetration depth Я = 3.6 X 10~5 cm. Estimates show that several properties of UBe13 can be described quite satisfactorily in terms of an ordinary superconductivity if UBe13 is assumed to have two groups of current carriers that interact with each other: "heavy" and "light" carriers.
