Title: **Kenji Sakane: Leading Innovator in Magnetic Materials**
Introduction
Kenji Sakane, based in Tokyo, Japan, is a prolific inventor renowned for his contributions to the field of magnetic materials. With an impressive portfolio of 36 patents, Sakane has significantly advanced technologies that enhance magnetic recording mediums, crucial for various applications in electronics and data storage.
Latest Patents
Among his latest innovations is the patent for an iron-based oxide magnetic powder and method for its production. The primary challenge addressed by this invention is to create magnetic powder with a narrow particle size distribution and minimal presence of fine particles that inadequately contribute to magnetic recording characteristics. The solution involves producing ε-type iron-based oxide magnetic powder through a wet method, integrating a tetraalkylammonium salt as a surface modifier under specific concentration and pH conditions. This process results in magnetic powder characterized by a finely tuned coercive force distribution, thereby enhancing the recording density of magnetic recording media.
Additionally, Sakane’s work on epsilon-type iron oxide magnetic particles focuses on improving particle size distribution. This invention provides magnetic powder with a number average particle diameter of major diameters ranging from 10 to 20 nm and a 90% cumulative particle diameter of 30 nm or less. The technology ensures a geometric standard deviation of major diameters is 1.45 or less, verified by transmission electron microscopy (TEM) observation.
