Brit IBM prof gets life-changing 'Tech Nobel' for work in spintronics
Joins Linus £$%^ Torvalds, Tim Berner-Lee as gong recipient
A Brit boffin at IBM’s Almaden Research Centre has won a Finnish prize for spintronics research which led to a thousandfold increase in disk capacity.
The €1m (£824,400) Millennium Technology prize has been awarded by the Technology Academy of Finland to Stuart Parkin, an IBM Fellow at Almaden where he manages the Magnetoelectronics group, and also a consulting professor at Stanford University.
The prize is awarded every two years for innovations that promote a better life. The general principles involved are:
- Awarded to groundbreaking technological innovations that enhance the quality of people’s lives in a sustainable manner
- The innovations have been applied in practice and are delivering extensive change now and in the future
- The innovations stimulate further cutting edge research and development in science and technology
Past winners include Sir Tim Berners-Lee, ‘im wot “invented” the world wide web, and Linus Torvalds of Linux infamy> fame.
The Finns gave Prof Parkin the award for “his discoveries, which have enabled a thousand-fold increase in the storage capacity of magnetic disk drives … thanks to the spintronic device.”
These “discoveries rely on magneto-resistive thin-film structures and the development of the giant magnetoresistance (GMR) spin-valve read head. Following the discovery of GMR in 1988, Parkin rapidly transformed this scientific observation into a practical data storage technology.”
Parkin also proposed magnetoresistive random-access memory (MRAM) in 1995 “based on magnetic tunnel junction (MTJ) memory cells,” according to the citation. “The MTJ, a close cousin of the GMR spin valve, has become standard in hard disk drive read heads.”
