Latest Patents

Among his latest patents, Takeuchi has developed a permanent magnetic material that aims to improve magnetic properties by retaining an amorphous phase in a quenched R–Fe–B permanent magnet. This innovative material comprises Fe as a major component, at least one lanthanoid element, R, and boron. The design includes 10 percent by area or less of a soft magnetic remaining amorphous phase, with the balance being a crystalline phase formed through heat treatment, which contains the R–Fe–B hard magnetic compound. Additionally, he has created a hard magnetic material that contains Fe as a main component, along with elements R and L, and B. Notably, at least 60% of the structure of this hard magnetic material consists of a fine crystalline phase with an average grain size of not more than 100 nm, while the remainder is composed of an amorphous phase.
