Realization of an N-shaped IVC of nanoscale metallic junctions using the antiferromagnetic transition
Yu. G. Naidyuk, K. Gloos, I. K. Yanson
We have observed at low temperatures (<8K) hysteretic I(V) characteristics for sub-mkm (~200nm) metallic break-junctions based on the heavy-fermion compound UPd2Al3. Degrading the…
Electronic shell effects and the stability of alkali nanowires
D. F. Urban, J. Bürki, A. I. Yanson +4
Experimental conductance histograms for Na nanowires are analyzed in detail and compared to recent theoretical results on the stability of cylindrical and elliptical nanowires, usi…
The antiferromagnetic transition of UPd2Al3 break-junctions: A new realization of N-shaped current-voltage characteristics
Yu. G. Naidyuk, K. Gloos, I. K. Yanson +1
We have investigated metallic break junctions of the heavy-fermion compound UPd2Al3 at low temperatures between 0.1K and 9K and in magnetic fields up to 8T. Both the current-voltag…
Shell-effects in heavy alkali-metal nanowires
A. I. Yanson, I. K. Yanson, J. M. van Ruitenbeek
We supplement our previous observations of the shell effect in alkali-metal nanowires (Li, Na, K) with data extended to the heavy alkalis Rb and Cs. Our observations include: i) a…
Enhancement of Kondo Temperature in Nanometer-Size Point Contacts
I. K. Yanson, V. V. Fisun, J. A. Mydosh +1
Point-contact spectroscopy is applied to study the energy dependence of paramagnetic impurities in noble metals. The samples are in the form of the so-called "mechanically controll…
