The capacity of computer memory could be boosted by exploiting tiny magnetic vortices known as skyrmions. That is the vision of physicists in the US, who have made individual skyrmion “bubbles” at room temperature by pushing magnetic domains through a narrow gap in a thin ferromagnetic-metal film – just as bubbles can be made by blowing on a soap-covered gap…..
