Magnetic bubbles and their observation in the electron microscope

摘要: Abstract In favourable circumstances magnetic domains can be made to move very rapidly through a ferromagnetic material in response an applied field. Recently this phenomenon has been exploited novel situation where cylindrical or ‘bubbles’ are used store and manipulate information binary form. Because of their small size high mobility bubbles may arranged form memory which storage density quickly accessed. recent years much effort gone into developing suitable materials support these the design optimum device configurations. Obviously there have many accompanying investigations physics bubble methods observing them. One important observational techniques, particularly for bubbles, is electron microscopy gives on structure unobtainable by any other method. This review seeks first explain what bubb...
