Executive summary: Giant magnetoresistance

German physicist Peter Grünberg discovered that thin layers of alternating metals react noticeably to even the most minute changes in magnetism, as a combination of magnetism and electron spin causes conductance in the stacks of magnetic layers the change. Called giant magnetoresistance (GMR), this is the principle that allows mind-bogglingly tiny particles to be used in data storage, generating the electrical signals that computers read. Advances in GMR have allowed hard disks to read and write much more data, leading to cheaper and more reliable computers, mp3 players, and countless further high-tech applications. Grünberg won the Nobel Prize in Physics in 2007, sharing the honor and cash stipend (about US$1.5 million) with French physicist Albert Fert, who conducted similar research concurrently but independently.
