Abstract
A multiterminal superconducting device with the S1 I S 2FIS3 structure (where S, I, and F denote a superconductor, an insulator, and a ferromagnetic material) is fabricated and characterized. Introducing a thin ferromagnetic layer into the middle electrode dramatically reduces parasitic back action of the acceptor junction (S 1 I S2) bias current on the injector junction (S 2 FI S3) current-voltage characteristic as compared with that for the formerly reported quiteron, a device exploiting similar operation principle.
