A method of preparing a permanent magnet nanocomposite. The method includes melting a precursor alloy having a hard magnetic phase and a magnetically soft phase. The hard magnetic phase has less than a stoichiometric amount of rare earth metal or noble metal. The melted precursor is cast into flakes and milled into a powder. The powder may then be pressure crystalized.
