Abstract
A nanoheterostructured permanent magnet includes a hard magnetic material and a soft magnetic material of which one inorganic component is a matrix, and of which the other inorganic component is three-dimensionally and periodically arranged in the matrix, in a shape selected from the group consisting of a spherical shape, a columnar shape, and a gyroid shape, the nanoheterostructured permanent magnet having a three-dimensional periodic structure whose average value of one unit length of a repeated structure is 1 nm to 100 nm.
