Peter Grünberg

1939–2018

Peter Grünberg (1939–2018) was a German physicist who discovered the giant magnetoresistance (GMR) effect in 1988, a breakthrough that revolutionized data storage and earned him the 2007 Nobel Prize in Physics. He spent most of his career at the Jülich Research Centre, where his work on magnetic multilayers laid the foundation for modern spintronics. Grünberg was known for his meticulous experimental approach and his ability to translate complex physical phenomena into practical applications.
