What material would work best as core material in a high frequency (>250 KHz) 3-phase, permanent magnet alternator? Thanks!

There are possible alternatives to laminated steel: soft ferrites, powder iron or amorphous steel; ferrites have low flux density capability, powder iron (e.g. Hoganas) has high hysteresis loss and only moderate flux density, and amorphous steel is almost impossible to manufacture into a slotted structure.
