Superconductivity in Silver Boron Intermetallic Compound

Critical current density and flux pinning in Zr0.96V0.04B2 superconductor with AlB2 structure

“…[3][4][5][6][7] In addition, AgB 2 and AuB 2 were predicted to have T c higher than 50 K from the theoretical estimates, 8,9 but recently much lower T c $ 7 K than theoretically predicted was found experimentally in AgB 2 thin films. 10 It should also be noted that, despite a favorable prediction of their high T c , [11][12][13][14] it is difficult to synthesize these materials with an AlB 2 structure.…”

A COMPARISON OF THE RESISTIVITY BEHAVIOR OF MgB2, AlB2 AND AgB2 SYSTEMS

“…Among several di-borides AgB 2 and AuB 2 were thought to be good candidates for higher T c [8]. There exists only one report of the observation of superconductivity of up to 6.7 K in a laser ablated AgB 2 thin film [9]. This value of T c is remarkably lower than theoretically predicted value of 59 K [8].…”

High-energy ball-milling for the synthesis of Ag–B superconducting materials

“…On the other hand, the same powder, but subsequently annealed at 300 • C, did not exhibit superconductivity. As well, no transition temperature was observed on the powder ball-milled for the prolonged milling time of 60 h, probably due to the exces- Superconductivity in Ag-B (1:2) was reported by Tomita et al with T c = 6.7 K in thin films which were prepared by a pulsed laser deposition method [9]. The reported T c value is much lower than the theoretically calculated one (T c = 59 K) [7].…”
