| 英文摘要 | The abnormal temperature characteristics of H-c in Alnico 8 alloys with thermomagnetic heat-treatment conditions are obtained at high temperature. The transmission electron microscopy (TEM) and Lorentz Fresnel images show that the a1 is the finite-nonlinear-dispersed magnetic nanoarray in spatial distribution. The angle dependence curves indicate the easy magnetization direction is still paralleled with the direction of columnar crystal growth and the magnetization reversal model is the incoherent rotation. Meanwhile the high temperature improves the magnetization reversal model from 30 degrees C to 240 degrees C and make it nearly steady above 240 degrees C. The reversal/irreversal reduced curves further reveal that improved magnetization reversal model makes a great effect on the magnetization reversal process. The B-H data and theoretical analysis illuminate that abnormal temperature characteristics of Hc from 30 degrees C to 240 degrees C primarily originates from the stronger effect of the improved magnetization reversal model. |
