Latest Patents

Tabuchi's latest patents include breakthroughs in Sm—Fe—N-based rare earth magnets. Her first patent focuses on a production method that results in magnets exhibiting superior resistance to demagnetization, incorporating a unique process that involves mixing SmFeN magnetic powder with a modifier powder. The procedure includes compression-molding the mixed powder in a magnetic field, pressure-sintering the body, and subsequently heat-treating the sintered body. This innovative method specifies that the diameter of the magnetic powder should be between 1.50 μm and 3.00 μm, while the zinc component in the modifier powder is carefully regulated between 6 mass % and 30 mass %.

The second patent further enhances her work by presenting a coated magnetic powder method. This approach also emphasizes the importance of specific parameters—such as the diameter of the coated magnetic powder (ranging from 1.50 μm to 3.00 μm) and a zinc content between 3 mass % and 15 mass %—to achieve improved performance under external magnetic fields at elevated temperatures.
