They had just announced that the 2007 Nobel Prize in Physics has been awarded to Albert Fert and Peter Grünberg for the discovery of the Giant Magnetoresistance.
Looks like this award went to the condensed matter physics area this time.
The family of material that goes under the giant and collosal magnetoresistance is as complicated as the high-Tc cuprates themselves. In some respect, they also share the same behavior and properties, especially in terms of crystal structures. So many of the understanding in one provides insight into the other. Often times, they were studied using the same methods and techniques.
