摘要:
Superconducting Ag-B (1: 2) materials were obtained by high-energy ball-milling. The planetary ball-milled powder exhibited a T-c = 8K which is higher than the previously reported value (T-c = 6.7 K) in thin films. Superconductivity appeared under a specific milling condition and a subsequent anneal suppressed superconducting transition. Although the existence of AgB2 was not clearly confirmed, the observed superconductivity might be related to this phase or other unspecified minor phases formed during milling. (C) 2010 Elsevier B.V.
