Cr-doped YMnO3 magnetic material and annealing method thereof
The invention discloses an annealing method of a Cr-doped YMnO3 magnetic material, and belongs to the technical field of magnetic materials. The annealing method comprises the following steps: Cr-doped YMnO3 magnetic material powder is provided; the Cr-doped YMnO3 magnetic material powder is subjected to compression molding, placed in air, sintered for 4-8 h at the temperature of 1100-1450 DEG C and then placed in an oxygen atmosphere to be annealed for 18-48 h at the temperature of 1200-1350 DEG C, and the annealed magnetic material is obtained. According to the method, the Cr-doped YMnO3 magnetic material is subjected to annealing treatment in the oxygen atmosphere, the ferromagnetic content of the magnetic material can be greatly increased, and the magnetic performance of the magnetic material is effectively enhanced.
本发明公开了一种Cr掺杂YMnO3磁性材料的退火方法，属于磁性材料技术领域。包括如下步骤：提供粉体的Cr掺杂YMnO3磁性材料；将粉体的Cr掺杂YMnO3磁性材料压制成型，置于空气中，于1100～1450℃烧结4～8h，再置于氧气气氛下，于1200～1350℃退火18～48h，即得退火后的磁性材料。本发明提供通过在氧气气氛下，对Cr掺杂YMnO3磁性材料进行退火处理，能够大幅度提升磁性材料铁磁含量，有效增强磁性材料的磁性能。
