Magnetic bubble memory ppt

WebBubble memoryis a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubblesor domains, each storing one bit of data. The material is arranged to form a series of parallel tracks that the bubbles can move along under the action of an external magnetic field. Webcurrent versus magnetic field phase diagram for skyrmion formation and we reveal the efficient manipulation of these dynamically created skyrmions, including depinning and motion. The demonstrated current-driven transformation from stripe domains to magnetic skyrmion bubbles could provide additional avenues for implementing skyrmion-based
