  Title Softening of the flux line lattice in Ge/Pb multilayers Type (up) Journal Article
  Year 1992 Publication Superconductor Science and Technology Abbreviated Journal  
  Volume 5 Issue 1S Pages  
  Keywords  
  Abstract The authors measured the critical current density Jc of artificially grown Ge/Pb multilayers as a function of the magnetic field H perpendicular to applied perpendicular to the layers. In these layered structures Jc(Hperpendicular to) rapidly drops to a pronounced minimum at a field H*perpendicular to, then increases through a broad maximum and finally decays to zero at H c2 perpendicular to. The systematic evolution of this minimum as a function of temperature, layer thickness and pinning strength allows us to conclude that this peculiar behavior is due to a thermally driven softening of the flux line lattice which can be related either to a magnetic decoupling or a melting of the vortex structure.

  Title Transition in the flux lattice of artificially layered superconductors Type (up) Journal Article
  Year 1991 Publication Physical Review Letters Abbreviated Journal  
  Volume 67 Issue 18 Pages 2577-2580  
  Keywords  
  Abstract We report a novel magnetic-field dependence of the critical-current density Jc in artificially grown Ge/Pb superlattices. In these layered structures Jc exhibits an unexpected minimum as a function of perpendicular applied field, unlike any ever observed in other superconductor systems. The systematic evolution of this minimum as a function of layer thicknesses, temperature and pinning strength is related to either flux-lattice decoupling or melting.

  Title Thermally induced transition in the vortex lattice of Ge/Pb multilayers Type (up) Journal Article
  Year 1991 Publication Physica C: Superconductivity and its applications Abbreviated Journal Phys C Supercond Appl  
  Volume 185-189 Issue PART 3 Pages 2061-2062  
  Keywords Germanium And Alloys; Lead And Alloys; Superconducting Films; Thermal Effects; Critical Currents; Multilayers; Metallic Films  
  Abstract We report on a novel magnetic field dependence of the critical current density of M.B.E. grown Ge/Pb insulator/superconductor multilayers. When the magnetic field is applied perpendicular to the layers, the critical current density Jc drops to a minimum, followed by a broad maximum before finally decaying monotonously to zezero with increasing magnetic field. The dependence of this effect on pinning strength, temperature, and layer thickness suggests either a thermally driven coupling/decoupling transition, or melting of the vortex lattice.
