SWITCHING ELEMENT AND MANUFACTURING METHOD THEREOF

摘要

Provided is a rewritable switching element that is capable of suppressing variations in element characteristics even when miniaturized. The switching element includes the following: a first and second electrode that can be metal-bridged; an ion conduction layer that is formed to fill in at least the space between the first and second electrodes and that comprises a material in which metal ionized by a magnetic field is mobile; a third electrode that is arranged facing the first and second electrodes and to which can be applied a magnetic field for ionizing or reducing metal; and an ion barrier layer comprising material in which metal ions are immobile. The ion barrier layer is arranged between the first and second electrodes and the third electrode.
