Defect Characterization and Testing of Skyrmion-Based Logic Circuits

Magnetic skyrmion is an emerging digital technology that provides ultra-high integration density and requires ultralow energy. Skyrmion is a magnetic pattern behaving like a stable pseudoparticle, created by a transverse current injection in ferromagnetic thin film. The state of a logic signal is represented by the presence (logic-l) or absence (logic-0) of a single skyrmion. Patterns on ferromagn...
