Abstract:
Unprecedented development of IT nowadays involves the necessity to explain for large human community the advanced science concepts. Now, there are needed hard disks with larger and larger capacity of memory and in the same time with smaller and smaller size. A GMR reading head is a perfect device for data reading from hard disks when the magnetic registered information has to be converted into electrical current. The most up to date reading devices are developed from GMR. This is why in 2007 the discovery of Giant Magnetorezistence by Albert Fert and Peter Grünberg won Nobel Prize in Physics. In this paper, we present a multimedia tool to explain GMR, made with common resources using MS Movie Maker or Flash. This tool can be used in a constructivist environment or as a cooperative learning tool integrated in different moments of physics classes.
