Engineers Use Voltage to Control Magnetic Memory

| December 9, 2014

This figure shows the principle behind using voltage to vary material properties. In this sandwich of materials, applying a voltage results in move of ions — electrically charged atoms — from the mean, functional layer of material into the target layer. This modifies some of the properties — magnetic, thermal, or optical — of the target material, and the changes remain after the voltage is removed.
