conInvestigation of Sr2RuO4-Pt tacts in an applied magnetic field
Artikel i vetenskaplig tidskrift, 2004

We investigated the spin-triplet superconductor Sr 2 RuO 4 by means of conductance measurements of normal conductor/ superconductor point contacts. We present results that show a linear dependence of the excess current as a function of temperature and applied magnetic fields over a wide range of the phase diagram. Applying a magnetic field larger than the upper critical field B c2 suppresses completely the features related to superconductivity and a conductance minimum at V = 0 occurs which becomes more pronounced with increasing field and persists even above T c up to several K. © 2003 Elsevier B.V.
