Giant Magnetoresistance Have you ever sat around on a rainy day contemplating your computer’s hard disk drive? Though often taken for granted, this magnetized device makes it possible to store and retrieve information digitally – in everything from video games to iPods to your personal computer. The first hard disk drives (HDDs) date back to [...]
Progress in the Study of Unusually Large Anisotropic Magnetoresistance Effects Our latest findings were published on August 25, 2009, in the Proceedings of the National Academy of Sciences. In cooperation with the National Institute of Materials Science of Japan, the Institute of Physics of the Chinese Academy of Sciences, Florida International University, and Louisiana State [...]
Magnetic Reed Switches for Position Location Stainless steel pneumatic cylinders that are equipped with an internal magnet can be used with the Reed Switch and GMR sensor. By accurately sensing the magnetic field of the piston when it passes beneath the sensor, its position is determined, and a feedback signal is created. GMR (Giant Magneto [...]
AMR vs. GMR Vs. TMR magnetic sensors Many companies are working hard in the design, development and fabrication of Anisotropic Magneto-Resistance (AMR), Giant Magneto-Resistance (GMR), and Magnetic Tunneling Junction (MTJ) magnetic thin film sensors. AMR vs. GMR Vs. TMR magnetic sensors Working with a variety of magnetic materials (see table below) AMS deposition [...]
