Signal Speed in Nanomagnetic Logic Chains
A time-resolved x-ray imaging technique directly observes signal propagation dynamics in nanomagnetic logic (NML) chains. The technique can assess NML reliability on fast time scales and help optimize chain engineering for this promising ultralow-power computing architecture. Read more »
Skyrmion Behavior Revealed by Two X-Ray Studies
Two research groups have recently published separate studies in which soft x-rays reveal how skyrmions—quasiparticles made up of spin vortices—react to external fields. Their work lays the foundation for understanding these fascinating constructs and eventually utilizing them in spintronic applications. Read more »
