Scaling of the Equilibrium Magnetization in the Mixed State of Type-II Superconductors
I. L. Landau, H. R. Ott
We discuss the analysis of mixed-state magnetization data of type-II superconductors using a recently developed scaling procedure. It is based on the fact that, if the Ginzburg-Lan…

We present a detailed study of the electronic transport properties on a single crystalline specimen of the moderately disordered heavy fermion system URhGe. For this materi…
Electronic transport through a quantum dot network
August Dorn, Thomas Ihn, Klaus Ensslin +2
The conductance through a finite quantum dot network is studied as a function of inter-dot coupling. As the coupling is reduced, the system undergoes a transition from the antidot…

Kondo Behavior of U in CaB
G. A. Wigger, E. Felder, S. Weyeneth +2
Replacing U for Ca in semiconducting CaB at the few at.% level induces metallic behaviour and Kondo-type phenomena at low temperatures, a rather unusual feature for U impuritie…
