Magnetic sandwich behind IT revolution
|
|
A small magnetic change can make a major difference to an electrical current. This is the basis of a responsive sensor that uses giant magnetoresistance. This effect opened the door for a completely new development in electronics, spintronics, and has in the last decade revolutionized techniques for scanning data on hard disks. |
Albert Fert and Peter Grünberg discovered the phenomenon of giant magnetoresistance simultaneously but independently in 1988. |
