Abstract
Advances in superconducting electronics, a leading beyond-CMOS technology, are limited by challenges related to power delivery and low integration density. The integration of ferromagnetism and superconductivity offers a potential solution for these issues, as demonstrated in superconducting digital circuits employing Josephson junctions with ferromagnetic barriers. In this review, the physics and dynamics of Josephson junctions with ferromagnetic barriers are presented, and experimental demonstrations of different types of ferromagnet-based junctions are summarized. Additionally, the application of junctions with ferromagnetic barriers in single flux quantum and half flux quantum circuits is reviewed, showing improvements in integration density and power consumption.
