The Potential of Spin
TDK is focusing attention on the power of the “spin” of electrons. By using “spintronics,” a technology that makes use of this phenomenon, TDK is conducting research and development of advanced electronic components that go beyond conventional wisdom.
Let’s observe the movement of spin!
It was the Einstein-de Haas effect experiment that made the “spin” of electrons visible by eye. In this exhibit, we re-create that experiment. By moving a magnet close to a permalloy metal rod, we can verify that the spins align, causing the rod to rotate.
For more details, check the exhibit panels.
Electrons have two properties: electric charge and spin. By harnessing the magnet-like property of electrons, which is known as spin, we can create electronic devices that operate quickly using less power and prevent data loss even after the power is turned off.
One product that makes use of spintronics is the TMR sensor. TDK’s TMR sensors are extremely sensitive and can detect movement of just 0.001 millimeters. These sensors are used in gaming keyboards, where a difference of just 1 millisecond can determine victory or defeat.
