Title: Akifumi Nakai: Innovator in Magnetic Force Measurement

Introduction

Akifumi Nakai is a distinguished inventor based in Kyoto, Japan. He has made significant contributions to the field of magnetic force measurement, showcasing his expertise through innovative patents. His work is particularly relevant in the study of magnetic domains, which has applications in various scientific and technological fields.

Latest Patents

Nakai holds a patent for an "Apparatus and method of obtaining field by measurement." This invention involves obtaining a distribution of magnetic force in a measurement plane above a sample with magnetic domains. By utilizing a Magnetic Force Microscope (MFM), he captures a magnetic force image and an auxiliary magnetic force image. The difference between these images is divided by the distance to obtain a magnetic force gradient image. Furthermore, both images are Fourier transformed and substituted into a three-dimensional field obtaining equation derived from the Laplace equation. This process allows for the accurate determination of the magnetic domains at the surface of the sample.
