"integrated into multi-periodic spin tunnel junction... stabilizes 2 exotic magnetic texture mixture (Bloch-type skyrmions/ bimerons) at room temperature, conducive for low power electron flow control... purify electron spin before reaches LED by passing through 4 sequential MgO tunneling barriers... skyrmions create nanoscale gradient magnetic field bending electron paths toward texture's core... spin-based logic, LEDs/ lasers for secure communication, scalable/ low-power data storage solutions"
