X-MINING 【R&D】 Fe-Ga Magnetostrictive Alloy Single Crystal

Magnetostrictive materials are used in actuators, sensors, and power generation devices. In recent years, the use of vibration power generation as a micro power source for IoT has been attracting attention, and the use of magnetostrictive materials as a material for vibration power generation devices is expected to expand.

Vibration power generation is a technology that generates energy from vibration using the piezoelectric effect, electromagnetic induction effect, electrostatic induction effect, and inverse magnetostriction effect, and is attracting attention as a micro power source for IoT. Our Fe-Ga Magnetostrictive Alloy Single Crystal are characterized by low variation in magnetostrictive properties, and exhibit excellent characteristics as magnetostrictive materials for vibration power generation devices that utilize the inverse magnetostriction effect.

Fe-Ga alloy is one of the iron-based magnetostrictive materials, which is attracting attention for vibration power generation applications because of its high magnetostriction coefficient (about 300ppm) and high mechanical properties. We have established a technology to fabricate high-quality Fe-Ga Magnetostrictive Alloy Single Crystal with low variation in magnetostrictive properties.
