Abstract
In aspects of the invention, a strongly correlated nonvolatile memory element is provided which exhibits phase transitions and nonvolatile switching functions through electrical means. In an aspect of the invention, a strongly correlated nonvolatile memory element is provided including, on a substrate, a channel layer, a gate electrode, a gate insulator, a source electrode, and a drain electrode. The channel layer includes a strongly correlated oxide thin film, and is formed of a perovskite type manganite which exhibits a charge-ordered phase or an orbital-ordered phase; the gate insulator is formed in contact with at least a portion of a surface or interface of the channel layer and is sandwiched between the channel layer and the gate electrode, and the source electrode and drain electrode are formed in contact with at least a portion of the channel layer.
