Coexisting non-trivial van der Waals magnetic orders enable field-free spin-orbit torque magnetization dynamics

Non-trivial magnetic orders are complex orders, which means they are not as simple as well-understood ones like ferromagnetism or antiferromagnetism.

However, it is extremely important for fundamental magnetism, and for the next generation of memory, logic, communication, and beyond von Neumann computing technologies.

Recently, researchers from Chalmers University of Technology (CUT) have reported non-trivial spin ordering with the coexistence of FM and AFM magnetic ordering in single two-dimensional van de Waals vdW magnet (Co0.5Fe0.5)5-xGeTe2 (CFGT) above room temperature.

This discovery makes it possible to demonstrate energy-efficient, magnetic field-free, and deterministic spin-orbit torque (SOT) switching of CFGT in heterostructure with Pt. Besides CUT, Uppsala University from Sweden and India Institute of Technology Ropar from India also contribute to the work.
