Magnetic monopoles erase data: Efficient and long-lived storage of information in magnetic vortices

Magnetic monopoles erase data: Efficient and long-lived storage of information in magnetic vortices: A physical particle postulated 80 years ago, could provide a decisive step toward the realization of novel, highly efficient data storage devices. Scientists have found that with magnetic monopoles in magnetic vortices, called skyrmions, information can be written and erased.
