Magnetic 2D materials, the new path to skyrmions?

Spintec recently teamed up with CNRS-Thales joint research unit UMPhy and China’s NIMTE to work on skyrmions. According to their results, the spin quasi-particles, which are heralded as the material for tomorrow’s magnetic memory, can be generated in transition metal dichalcogenide (TMD) monolayers.  

Their work focused on Janus MnSeTe and MnSTe TMDs: In these materials, a layer of manganese is placed between two different chalcogen layers to create the asymmetry necessary for the magnetic interactions that produce skyrmions. A magnetic field is applied at temperatures up to 150 K to stabilize the skyrmions.

Lab experiments are already underway to test this new approach. The overriding objective is to broaden the number of potential skyrmion materials beyond just metal magnetic multilayers.
