Abstract
A data storage method includes writing data to a ferromagnetic shape-memory material in its ferromagnetic state, the material exhibiting more than two stable states. A data storage device includes a non-volatile memory element containing a ferromagnetic shape-memory alloy in a martensite state, the shape-memory alloy being ferromagnetic in a plurality of stable states of the memory element.
