About:
ANSL (Applied nano-spintronics laboratory) explores new physical phenomena in magnetic materials based on spintronics, including spin-orbit torque induced by orbital currents and spin currents generated in chiral structures. Through these studies, ANSL aims to advance magnetic random-access memory (MRAM) and its applications in neuromorphic computing, stochastic computing, and security devices such as physical unclonable functions.
