Variations in Stochastic Magnetic Tunnel Junctions
physica status solidi (a), Volume 223, Issue 14, 22 July 2026.This work presents a reproducible fabrication method for nanoscale stochastic magnetic tunnel junctions (s‐MTJs) using undercut‐assisted e‐beam lithography, end‐point‐controlled etching, and in situ passivation. The study identifies key variation sources, such as static characteristic variations in TMR, resistance, coercive field, and loop shift ...
