1. A FeNi ordered alloy powder comprising:
a plurality of particles having an L10 type ordered structure, wherein:
a size of the particles is in a range between 200 nm and 500 nm,
a volume fraction of a pore in the particles with respect to a volume of the particles having an unit of vol. % is 5% or less, and
the particles are in an isolated state in which adjacent particles are isolated from each other by not being attracted or integrated to each other, by being physically independent from each other, and by being separable from each other.
