Abstract
A method of initializing a multiferroic element for obtaining a stable element operation includes applying at least one selected from a group consisting of an electric field and a magnetic field to the multiferroic element under a temperature condition equal to or higher than a phase transition temperature. The multiferroic element has a laminated structural body including a first alloy layer and a second alloy layer. The first alloy layer is formed by using any of antimony-tellurium, bismuth-tellurium and bismuth-selenium as a principal component. The second alloy layer is laminated on the first alloy layer, and formed by using a compound represented by the following general formula (1) as a principal component. The second alloy layer is configured to undergo phase transition between a reset phase and a set phase. Electric polarization is not caused in the reset phase, but caused in the set phase. The second alloy layer undergoes the phase transition from the reset phase to the set phase at the phase transition temperature.
