Abstract

Tb-Dy-Fe alloys with 〈1 1 1〉 preferred orientation were prepared by directional solidification under high magnetic fields. The relationship between the 〈1 1 1〉 orientation degree, magnetic domain structure, magnetostrictive properties, and magnetization behavior was investigated. In the low-field region, the domain structure played a crucial role in enhancing the magnetic properties; whereas in the high-field region, the 〈1 1 1〉 orientation degree became more substantial. If the magnetic phase can be induced to orient along the 〈1 1 1〉 direction and the magnetic domain structure can be optimized by a high magnetic field, the magnetostrictive properties of the alloys will be greatly improved.

高磁场下定向凝固铽镝铁合金结晶取向和磁畴结构诱导的磁致伸缩响应

在高磁场下通过定向凝固制备了具有〈1 1 1〉优先取向的铽镝铁合金。研究了〈1 1 1〉取向度、磁畴结构、磁致伸缩特性和磁化行为之间的关系。在低磁场区域，磁畴结构在增强磁性能方面起着关键作用；而在高磁场区域，〈1 1 1〉取向度变得更加重要。如果能通过高磁场诱导磁相沿〈1 1 1〉方向取向并优化磁畴结构，合金的磁致伸缩特性将得到极大改善。
