Magnetization process in NANOPERM-type nanocrystalline alloy

The magnetization process in nanocrystalline Fe85.1Mo0.5Zr3.3Nb3.3B6.8Cu1 alloy was studied by varying the AC and/or DC magnetic field amplitude in the frequency range from 0.1 kHz to 1 MHz. When a small magnetic field is applied, the magnetization process is dominated by the domain wall bulging; and when the applied field is over the threshold field (<f>Hp</f>), the magnetization process is dominated by the domain wall bulging and displacement. A small longitudinally DC magnetic field will lead to an increase in the magnetization process, a high DC field produces a decrease in the magnetization process. [Copyright &y& Elsevier]
