(Color online) MELRAM cell configuration: The magnetic element and electrodes are embedded in a piezoelectric matrix.
(Color online) Magnetic free energy profiles (arbitrary units.) of the system as a function of the magnetization angle for three stress states. (—) No stress: two stable positions are defined for 90° and 180°. (Squares) Compressive stress along anisotropy along OY, only the 90° position is stable. (Circles) Tensile stress along anisotropy along OX, only the 180° position is stable.
Magnetic element strain in the piezoelectric matrix along the OX axis for three values of the driving voltage. Apparent deformation of the element is exaggerated. White: tensile strain, black: compressive strain.
Magnetic element strain in the piezoelectric matrix along the OY axis for three values of the driving voltage. Apparent deformation of the element is exaggerated.
(Color online) Effect of stress on magnetization. (Left) Tensile stress is generated, magnetization is switched and set in position 2. (Right) Compressive stress is generated, magnetization is set in position 1.
