What is Giant magnetoresistance (GMR)?
Q: What is Giant magnetoresistance (GMR)?
A: GMR is a small magnetic effect found in thin layers of iron and other materials that is used to read and write information in hard drives.
Q: How is the GMR effect measured?
A: The GMR effect can be measured when a magnet is used to change the flow of electricity.
Q: Who were awarded the 2007 Nobel Prize in physics for the discovery of GMR?
A: Albert Fert and Peter Grünberg were awarded the 2007 Nobel Prize in physics for the discovery of GMR.
Q: What is the importance of the GMR effect?
A: The GMR effect is important for the functioning of hard drives and is used for reading and writing information.
Q: What materials can the GMR effect be found in?
A: The GMR effect can be found in thin layers of iron and other materials.
Q: Can the GMR effect be seen with the naked eye?
A: No, the GMR effect is very small and cannot be seen with the naked eye.
Q: What is the significance of the discovery of GMR?
A: The discovery of GMR was significant enough to warrant a Nobel Prize in physics, as it has important practical applications in hard drive technology.
