Controlling skyrmion size in the alloy FePd1−xPtxMo3N

After discovering a new magnetic host of skyrmion states, UC Santa Barbara IRG-1 researchers were able to show that chemically alloying the compound FePd1−xPtxMo3N allows for the size of the skyrmion defects to be controlled while still preserving their stability.  Skyrmion states are broadly sought in new materials due to their potential uses in low power memory devices and other spin-based electronics.
