Moving magnetic domain walls with sound alone
Alejandro Rivelles, Rocío Yanes, Luis Torres +18
Surface Acoustic Waves (SAW) have been used in spintronic applications to decrease the magnetic field or the electric current required to act on the magnetization. A common belief…
Tailoring the energy landscape of a Bloch point singularity with curvature
Sandra Ruiz-Gomez, Claas Abert, Pamela Morales-Fernández +14
Topological defects, or singularities, play a key role in the statics and dynamics of complex systems. In magnetism, Bloch point singularities represent point defects that mediate…
