R. Haussler et al., POINT CONTACTS WITH THE AMORPHOUS SUPERCONDUCTOR (MO0.55RU0.45)(0.8)P-0.2 IN A MAGNETIC-FIELD, Physica. B, Condensed matter, 218(1-4), 1996, pp. 197-199
Current-voltage (I-V) characteristics of point contacts between the am
orphous superconductor (Mo0.55Ru0.45)(0.8)P-0.2 and Ag show distinct f
eatures which are associated with reaching of B-cl at the periphery of
the constriction by the transport current according to Silsbee's rule
and the motion of flux vortices. In the dV/dI curves of some contacts
additional features caused by exceeding the pair-breaking current den
sity and probably Andreev reflection are observed. All features vanish
at the bulk critical temperature T-c or the bulk upper critical field
B-c2.
