On the sintered iron-12.5 chromium magnetic alloys with and without 0.1-0.2 percent mixed oxide powders composed of SiO<SUB>2</SUB>, CaO and Al<SUB>2</SUB>O<SUB>3</SUB>, the change of hysteresis curves in alternating magnetic field was measured to be compared with the melted alloy. It is confirmed that the magnetic properties of the sintered alloy added oxide are improved in alternating magnetic field such as maximum magnetic flux density, amplitude relative permeability and power losses in compared with the case of the no-oxide addition. And the magnetic properties of sintered alloys exceed the melted alloy in alternating magnetic field over 1kHz in spite of the inferior in direct magnetic field.
