Latest Patents

Fukamichi's latest patents demonstrate his groundbreaking approach to magnetic materials. One notable patent is for a magnetic material designed specifically for magnetic refrigeration. This innovative material features an NaZn-type crystalline structure, with iron (Fe) as a principal element, substituted for zinc (Zn), and incorporates hydrogen (H) at varying atomic percentages. This magnetic material displays a substantial entropy change at room temperature and eliminates thermal hysteresis during magnetic phase transitions, allowing for stable operation in refrigeration cycles.

Another recent patent involves a writing method for magnetic immovable memory, specifically utilizing a lattice-structured underlayer made from a ferroelectric material with a piezoelectric effect. This underlayer is strategically formed on a substrate. By applying voltage to specific columns and rows of the underlayer, stress is generated at the crossing points, causing magnetization reversal in the magnetic films located on those points through the magnetoelastic effect. This innovative process is crucial for enhancing the capabilities of magnetoresistive random-access memory (MRAM).
