The resistivity of saturated magnetic flux
Fe- - Sm- - O and Fe - alloy film - Ho - - O alloy membranes examined their resistivity of Fe content. Determination for annealing at 400 ℃ temperature resistance of the alloy membrane. The measurement result is shown in figure 2. 3. In the figure. In figure 3, Fe - Sm- O alloy membrane ( - 。 The small circle - 。 The small circle - ） Said the Fe - Ho - O alloy membrane ( - 。 Solid - 。 ） Said. Circle - 。 ） 。 For two kinds of alloy membrane, with fewer Fe content, resistivity are increased. In a rotating magnetic field under the temperature Of 400 ℃ with the Fed Hfe Of alloy membrane composed Of annealing six hours, to check its saturation magnetic flux density and resistivity Of Hf content. In checking the Fed alloy membrane of Hfe, Hf content, Fe content in a 45. 6 atom % above, O content in 33. 5 to 36. The scope of 9 atom %. The result is shown in figure 2 and 3. 4 and 5. Hf content increased, leading to decreased saturation magnetic flux density. In addition, by increasing the content of Hf, the resistivity increases. In addition, before the heat treatment, checked with the Fed Hfe Of composition Of the alloy membrane under the saturation magnetic flux density and different composition ratio Of resistivity. The measurement result is shown in figure 2. 6. In the figure. In figure 6, indicates the point (composition than 。 ） The value is above the resistivity ( μΩ. cm） Here are the values of the saturation magnetic flux density is ( T） 。 Showed after heat treatment in the field of soft magnetic alloys coercive force and magnetic permeability, and saturation magnetic flux density and resistivity.
