烧结锶铁氧体的极图分析
Pole Figure Analysis of Sintered Strontium Ferrite
摘要
Abstract
Sintered strontium ferrites were prepared by wet compaction under different applied magnetic fields and sintered at 1 190 ℃ for 2 h. An X-ray pole figure was used to analyse the texture character of the magnets. The method to describe the alignment degree was proposed based on the Stoner-Wohlfarth model. Diffraction intensity of {001} crystal planes for the samples with magnetic compact is higher than that without magnetic field applied. It is indicated that the (008) pole figure can be used to measure alignment degree of these sintered ferrites. The alignment degree of these ferrites enhances with the increase of magnetic field. The alignment degree reaches 78.3% at the applied magnetic field of 600 kA/m. The (107) pole figure is also attempted to measure the crystal alignment of ferrites.关键词
