| Abstract | This paper presents a record of the miscellaneous transfer function patterns displayed during the evolutional processes of forming an RF-SQUID with a bulk Tl2Ba2Ca2Cu3O10+ High Temperature Superconducting (HTSC) material. These special physical phenomena connected with HTC superconductivity, showed observable regularity. From our observations we conclude that these patterns are due to multi-quantum transitions. Variational patterns continued until the critical size of the weak link (~ 0.05 mm) was reached where only one single flux quantum period was present. Study of such regularity on pattern change could be helpful towards the understanding of HTSC RF-SQUID. It is worth mentioning that we are the first to report this behavior for SQUIDs made from Thallium compounds. PACS No. 75.50+r, 85.25Dg |
