Title:
Surface {{Sensitive Superconductivity}} in {{ZrZn2}} 
Abstract:
We show that spark erosion of the weak itinerant ferromagnet ZrZn2 induces a near surface superconducting layer. Surface analysis suggests that spark erosion causes zinc depletion of the surface. The pressure dependence of the superconducting transition temperature means that it is unlikely that observed superconductivity is due to elemental Zn or Zr produced during the spark erosion. Possible explanations of the observed superconductivity include the presence of other phases or strains in a lay...    »
