In our electronic world, since the discovery of electron by J J Thomson in 1897, scientists have been working strenuously to build the Digital World that we enjoy today. To satisfy a common man need, researchers have been scratching the very basis of electronics – Electron.
All that we are using today is the flow of a bundle of electrons to determine the electronic outcome instead of the basic property of electron, which is to Spin. They started exploiting this property leading to the rise of a new technology – Spintronics.
Spintronics came into lime light in 1988 when French and German physicists Albert Fert et al (in Paris) and Peter Grunberg et al (in Jullich) independently discovered the Giant Magneto Resistance (GMR). This discovery is considered to be the birth of spintronics. The two physicists have earned a number of prestigious prizes and awards for their discovery and contribution in the field of spintronics, including the 2007 Noble Prize in Physics.
