Abstract

PURPOSE:To obtain the titled element withstanding the repeated cycles covering normal temperature and a super-low temperature by a method wherein the first and the second super-conducting material layers are composed of the probeskite type oxide shown by BaPb1-XBiXO3 and a barrier layer is composed of a probeskite type oxide containing Ba or Sr. CONSTITUTION:The first belt-shaped super-conducting material layer 2 is formed on a substrate 1 and a tunnel-junction type Josephson element is obtained by bonding the second super-conducting material layer 4 on the end section of said layer 2. To be more precise, the substrate 1 is covered by the first super-conducting material layer 1 consisted of a probeskite type oxide shown by BaPb1-XBiXO3 (0.05<=X<= 0.3) by performing a sputtering and a subsequent heat treatment while the substrate 1 is being cooled, and a barrier layer 3 consisted of a probeskite type oxide of SrPb1-XBiXO3 (0<=X<=0.3) is formed on the end section of the layer 1, while it is being cooled. The second super-conducting material layer 4 is similarly provided on said layer 3.
