Microstructure and magnetic properties of soft magnetic powder cores of amorphous and nanocrystalline alloys

► Amorphous and nanocrystalline MPCs were successfully produced and compared. ► μe of both kinds of MPC keeps unchanged up to 1 MHz. ► Amorphous MPC has lower PCV at lower frequency, while nanocrystalline MPC at high frequency. ► The nanocrystalline MPC has better DC-bias property. ► Their microstructures and soft magnetic properties were also investigated and compared.
