Element exploiting magnetic material and addressing method therefor |
摘要 |
An element that is able to control magnetization without applying a magnetic field from outside. A magnetized area formed of a ferromagnetic material is split by a spacer area of a composite material including a magnetic material and a semiconductor material. A stimulus is applied from outside to the spacer area to change the magnetic interaction between split magnetized areas to control the magnetization of the magnetized areas. Alternatively, a layered assembly made up of an electrically conductive layer containing an electrically conductive material and plural magnetic layers is provided so that the electrically conductive layer is arranged between the magnetic layers. The current is caused to flow through the electrically conductive layer to change the magnetic coupling state between the magnetic layers to control the direction of magnetization between the magnetic layers.
