Ag-B Thin Films Prepared by Magnetron Sputtering Academic Article uri icon

abstract

  • The discovery of the new superconductor MgB 2 with critical temperature of T c= 39 K stimulated great activity in search for materials with higher T c. Theoretical works predicted the possibility of obtaining such superconducting materials in other borides also, in particular in AgB 2. It was predicted in these works that diborides of metals having the AlB 2 type structure, among them AgB 2 may have superconductivity with a T c higher than 39 K. In an early very short report the lattice parameters of AgB 2 were evaluated in a synthesized specimen. However, no other indication exists that AgB 2 was ever produced. We report the preliminary results of our attempts to prepare AgB 2 films.
