Today, compact and fast hard discs are a useful tool for the information society. Our data, which are becoming more and more extensive thanks to the music and video industry, are just a few clicks away. This convenient access has become possible through a discovery which was made at Research Centre Jülich not so long ago.

At the end of the 80s, Peter Grünberg discovered that the electrical resistance of thin magnetic layers can be greatly changed through external magnetic fields. Since the mid-nineties, the so-called GMR or giant magnetic resistance effect has been used in all common hard discs to read magnetic bits and bytes. The effect is based on the quantum-mechanical combination of electron spins in the material layers.

In only ten years, the GMR effect has made its way from the laboratory to the consumer and is now used daily a billion of times.
