Abstract
A method of increasing volume ratio of magnetic particles in a MnBi alloy includes operating a jet miller fed with a MnBi alloy powder containing magnetic particles and non-magnetic particles with gas flow parameters selected such that, only for the magnetic particles, a gas drag force is greater than a centrifugal force within the jet miller to separate the magnetic particles from the non-magnetic particles.
